The Wolf at the Door BY RANCE HERREN, CFPSD, CFPECS, CFPMT, CFPAI, 2016 IFPS President

Here we go – another year and another IFPS president. And that is a good thing. The many new members serving on the Board of Directors bring new perspective and fresh ideas that are key in defining and promoting the Society’s mission to advance professionalism, education, and certification in the fluid power industry. Traditionally, the “Notable Words” column from the incoming president highlights the Society’s plans for the coming year. I can happily report that in 2016, a number of initiatives are underway, including the release of revised study manuals and tests for the Hydraulic, Pneumatic, and Electronic Controls Specialist certifications, development of the Electronic Controls Technician certification, continuing outreach to fluid power students and professionals through scholarships and educational programs, and lots of other really cool stuff. So now that we have the formality out of the way, please allow me to get on my soapbox. We are in a crisis. Let me say that again. WE ARE IN A CRISIS! Much like the hard sciences and the skilled trades, the fluid power industry is suffering a drain on the talent pool that is alarming, to say the least. The number of individuals coming into and staying in the industry compared with those leaving or retiring is strikingly disproportionate. And if not addressed, the encroachment from competing technologies will only erode the footprint of fluid power as a dominant force in mechanical transmission of power and motion control. In the recent Republican debate, Senator Marco Rubio’s comment that “We need more welders and less philosophers” has certainly resonated with a lot of people, regardless of their political leanings. (I will add that we need a lot more fluid power professionals, too.) This is not a jab at the liberal arts, but it is somewhat disingenuous to not recognize there are a lot of very smart people with university educations preparing to enter the workforce with abilities that do not align with the needs of the marketplace. Or more plainly put, in many instances, we as a nation are over-educated and under-skilled. The impact of this is that the younger talent needed in the skilled trades is not keeping pace with the demand as older employees leave the workplace. And as increasingly difficult as it will be to find this new talent, it will even be more difficult to transfer the knowledge base unless they have the necessary skills to understand and apply it. In a recent study by Deloitte Development and the Manufacturing Institute, The Skills Gap in U.S. Manufacturing 2015 and Beyond, it was noted that “The areas of skilled production (machinists, operators, and technicians) will be the hardest hit, and considering skilled production occupations account for over 50% of the total manufacturing workforce, worker shortages in this category will present a significant challenge to companies.” And in my experience, this trend cuts deeper and wider in fluid power than just about any industry. So where does this leave us in fluid power? If we as an industry do not recognize the wolf at the door and fail to invest in the development of our employees, including training and certification, we are inadvertently promoting the industry’s and maybe even our own company’s demise. At the same time, there is also great opportunity for those willing to learn new skills and to work hard in applying them. According to the National Association of Manufacturers, in 2013, an average manufacturing income was 20% higher than compared to what an average worker earned in other occupations. And I am here to tell you those kinds of careers are available in fluid power if you are willing to work. So as we embark on a new year and the challenges ahead, the only certainty we have, the only constant, is change. Or better put, in the words of the greatest of all philosophers Yogi Berra: “The future ain’t what it used to be.” Rance Herren is the manager of hydraulic systems and controls for the Rig Solutions division of National Oilwell Varco.

PIRTEK PIRTEK was first established in Australia in 1980 and is a leader in on-site hydraulic hose replacement with nearly 400 locations in 23 countries and more than 2,000 mobile hose shops. In the United States, the company currently has 54 locations and plans to top 200 locations nationally by the end of the decade. PIRTEK’s mission is to provide franchisees with the opportunity to be in business for themselves, but not by themselves. Gwyn O’Kane, CFPE, is vice president of franchise development at PIRTEK and an active member of IFPS Chapter 49 in central Florida. In this interview, Mr. O’Kane tells the Journal about how IFPS certification ensures the safety and success of PIRTEK and its employees.

Our uniqueness stems from two distinct areas. First, our service technicians are available to replace failed hoses on industrial and mobile hydraulic machines, on-site, 24-hours a day, 365 days a year. We offer an estimated time of arrival on-site in less than one hour from a customer’s call to the performance of service in the specific service area. Once onsite, technicians remove failed hoses; manufacture a replacement; and then clean, test, tag, and install it all on the job site. We also perform installations and offer preventative maintenance programs to reduce our customer’s downtime and expenses that result from hose failure. Second, PIRTEK is a franchise business format, which makes us very unique in the industry. We also sell and service our own hydraulic hoses, further differentiating ourselves within the franchise industry. We are an industrial business-to-business franchise opportunity. Our owners operate a “hose service center,” offering trade counter service and a fleet of mobile hose vans all from the same location.

What makes PIRTEK stand out in the industry?

I began working at PIRTEK as a mobile sales and service technician in 1989 after working for Ford Motor Co. in New Zealand as an engineering cadet. At the Ford factory, I was merely a small cog in a big machine. But when I joined PIRTEK, I fell in love with the small team/family environment of a PIRTEK center. I am very proud of the fact that after 18 years in the United States, we have many employees within our organization who have been with us for over a decade. PIRTEK has provided many employees with a great place to work, an excellent career opportunity, and an entrepreneurial opportunity for those who desire to own their own business.

What makes PIRTEK such an attractive place to work?

The IFPS has become immensely important to our organization. We are proud to be experts in hoses and fittings. The Connector and Conductor certification (C&C) provided a means to validate that expertise. The IFPS C&C shirt patch that our team members earn once they become certified has become a badge of honor for our technicians. From a company perspective, the IFPS logo has become a symbol to our customers that we hold ourselves to the highest international standard and that they are working with a professional company. The single most important reason that we support the IFPS and certification is that it helps keep our employees safe. I would encourage everyone involved in the fluid power industry to get certified for this reason alone, because nothing is more important than ensuring we all return home safely to our families every night.

Why is IFPS certification important to PIRTEK?

I am sure most, if not all, involved in the fluid power industry would agree that fluid power is more complex and has the potential to be more hazardous than the automotive, plumbing, or electrical industries. To a certain extent, fluid power requires us to be familiar with all of these industries. These industries are heavily regulated with certifications and licensing requirements. To a large degree, we are an industry that is self-regulated, and for that reason, it is incumbent upon us to support programs like IFPS certification to ensure that we remain safe and maintain a high level of professionalism in the industry.

Why is IFPS certification important to the fluid power industry as whole?



Global Manufacturing Update BY CHAD MOUTRAY, Chief Economist, National Association of Manufacturers

November 2015 – There were signs of progress in the global economy in October, but manufacturers continued to face headwinds. On the positive side, J.P. Morgan Global Manufacturing PMI increased from 50.7 in September to 51.4 in October, its highest level since March. This provided a little encouragement after falling to a two-year low in August and September. In particular, this report reflected better data in the United States, Japan, and the United Kingdom. Despite this progress, many of the underlying economic challenges have not changed much over the past few months. Along those lines, there were five countries in the top 10 markets for U.S.-manufactured goods that remain mired in contraction territory. These include Brazil, Canada, China, Hong Kong, and South Korea.

Brazil’s manufacturing activity deteriorated at its fastest pace since March 2009, while China and Hong Kong eased in their rates of decline for the month. Still, Chinese economic growth has decelerated significantly, including industrial production, with President Xi Jinping reducing China’s real GDP target to 6.5%, down from 7.0% earlier in the year. Indeed, slowing activity in China has continued to prompt financial markets around the world to worry more about global economic growth. Those problems are most evident in the emerging markets, where manufacturing activity has now contracted for seven straight months. Closer to home, manufacturers in Canada continue to struggle on the drop in crude oil prices, with that nation’s struggles playing a significant role in recent elections, which saw Justin Trudeau capture the majority of votes against incumbent Prime Minister Stephen Harper. In contrast to other regions, Europe has been trending in the right direction. The Markit Eurozone Manufacturing PMI increased slightly from 52.0 to 52.3, and in general, there has been considerable progress since the sector was essentially stagnant in November 2014 (50.1). There were modest expansions in October for manufacturing new orders, output, and exports. The United Kingdom made the most progress in October, with its PMI increasing to the highest level since June 2014. Meanwhile, Greece continued to contract, even as it notched its best reading since May. We will get provisional real GDP figures on November 13 for the third quarter, which are expected to be around 1.7% year-over-year. This would be an improvement from second-quarter growth of 1.5% on a year-over-year basis. Deflation has been a major concern for the European Central Bank this year, spurring suggestions of increased quantitative easing moves soon. Indeed, there has been talk of more monetary stimulus by the

end of this year. When you combine that news with the growing consensus that the Federal Reserve will begin to raise short-term interest rates at its December meeting, it is not hard to see why the U.S. dollar continues to strengthen. The dollar has appreciated more than 24% since the end of June 2014, making it more difficult for manufacturers in the United States to grow their exports. Weaknesses abroad are another factor challenging international trade right now. According to updated data from TradeStats Express through the third quarter, manufactured goods exports have fallen 1.5% year-to-date in 2015 relative to the same time period in 2014. This trend extends to the top four markets for U.S.-manufactured goods: Canada (down 8.6%), Mexico (down 0.3%), China (down 0.4%), and Japan (down 3.6%). In addition, exports to Asia, Europe, and South America were down 1.9%, 3.0%, and 14.7% respectively, year-to-date. Nonetheless, the U.S. trade deficit narrowed in September on an increase in goods exports and a decrease in goods imports. In addition, the petroleum trade deficit fell to $5.6 billion, with petroleum imports at their lowest level since May 2004. One month after announcing the conclusion of the Trans-Pacific Partnership (TPP) agreement, the United States released the text of the TPP and moved forward toward signing. Some progress was made during the 11th round of Transatlantic Trade and Investment Partnership (TTIP) talks between the United States and the European Union (EU). The House approved a reauthorization of the U.S. Export-Import (Ex-Im) Bank as part of a highway bill, which is now headed to conference. Customs legislation remains under construction, and negotiations continue on environmental and information technology goods. Excerpt reprinted with permission. For the full report, visit

IFPS ELECTRONIC CONTROLS SPECIALIST CERTIFICATION UPDATE Subject matter experts have been hard at work revising the IFPS Electronic Controls Specialist Certification (study manual, pre-test, written test) with expectations to be re-released the first quarter of 2016. This certification is designed to review and test understanding, specification, and application of the full breadth of electronics used in the fluid power industry from simple sensors and limits to HMIs, controllers, and networks. It includes a brief review of applicable pneumatic and hydraulic principles, as well as in-depth examples of the electronics for both mobile and industrial fluid power equipment. The Electronic Controls Specialist certification requires a three (3)-hour written test. This certification will be followed by the development of Mobile Electronic Controls and Industrial Electronic Controls certifications. CIRCLE 411

NFPA Board Continues Focus on Growing the Fluid Power Workforce BY ERIC LANKE, NFPA CEO As our Chairman Jeff Stuart expressed earlier this year, NFPA and its Board of Directors are increasing its focus on a set of clear, high-level objectives—what we’re coming to refer to as “ends” statements, because they describe the major ends or outcomes we wish to achieve. Of the six statements currently identified, three of them deal exclusively with what the NFPA membership consistently ranks as its number-one challenge: growing the fluid power workforce: ƒƒ NFPA fosters awareness and involvement of middle and high school students, helping them understand fluid power’s potential as a technology and choose fluid power as a career path. ƒƒ NFPA helps increase the number of technically trained people capable of integrating and applying fluid power, and connects them to careers in the fluid power industry. ƒƒ NFPA supports universities in the development of fundamental fluid power knowledge and connects our industry to an increasing number of scientific and engineering leaders in our field. At their most recent meeting in October 2015, the NFPA Board again deepened its focus in these three areas, recognizing both our growing success in each and advancing several new program concepts that could help move the needle even farther.

Fluid Power Challenge This program for middle school students continues to grow and has established itself as our primary outreach activity to young people, introducing them to fluid power technology and careers in the fluid power industry. Last year, 1,450 middle school students participated in 14 Fluid Power Challenge events, where they built fluid power mechanisms out of simple materials and operated them in a series of timed competitions, and 2,369 additional middle school students participated in Fluid Power Challenge-related classroom activities at 28 schools. A growing number of NFPA members are running Challenges in their local communities to open doors with school districts and make ties to local technical schools, where many of the Challenge events are held. As we look to the future growth of this program, we’ll be launching a new Fluid Power Challenge website and online community, where we can more readily build a nationwide network of teachers, students, and parents interested and excited about fluid power as a pathway to STEM education and careers. High School Fluid Power Challenge With this success at the middle school level, we have recognized the need and will be developing a companion program for the high school environment. Students first exposed to fluid power in middle school need to encounter it again in high school, hopefully in some kind of hands-on challenge, not with the wooden structures and plastic syringes they used in middle school, but with the actual fluid power components and systems in-use in the engineering marketplace they are quickly approaching. Many engineering competitions and curricula exist for these STEM-minded high school students—FIRST Robotics, SkillsUSA, and Project Lead the Way being just a few examples—and our plan is to explore a possible partnership with one of those providers to greatly accelerate fluid power’s distribution into that educational landscape. FOR TECHNICALLY TRAINED PEOPLE

Center for Advanced Fluid Power Technical Education NFPA’s focus on 2-year technical schools and community colleges is increasing sub-

stantially as we recognize the pressing need for more employees with the technical degrees and skills that these schools provide. For several years now, our Foundation has been awarding $25K grants to these schools to buy new fluid power trainers and build new fluid power curriculum around them, but the Board has now embraced an even more ambitious plan. We’re in the initial planning phases of an exciting new funding opportunity, in which significant dollars from the National Science Foundation would be used to create and support a nationwide network of 2-year technical schools and community colleges with dedicated fluid power education and training programs. As part of this program, regionally clustered industry partners would need to work inside of local high schools to promote fluid power and direct students to one of these “Centers for Advanced Fluid Power Technical Education,” coach them through their training period, and then hire them upon graduation. FOR UNIVERSITIES

Center for Compact and Efficient Fluid Power NFPA’s partnership with the CCEFP, the network of fluid power research laboratories, academic faculty, graduate, and undergraduate students at seven universities, continues to grow and deliver results for the fluid power industry. Since its inception in 2007, the CCEFP has added more than 100,000 square feet of fluid power lab space to its universities, increased the number of fluid power advanced degrees awarded by those universities by more than 500%, increased the number of fluid power educators on those campuses by a factor of 10, and engaged more than 13,000 university students in a variety of workforce development programs, including ƒƒ Pre-competitive Fluid Power Research Projects. Directed by industry to the topics most needed, these projects help build fluid power infrastructure at CCEFP schools and engage promising students in the study of fluid power. To date, 225 individual projects have been funded, enabling more than 250 students to earn their Masters or PhD degrees. Forty-five percent of these students go on to work in the fluid power industry. ƒƒ Fluid Power Scholars Program. An in-

ternship program where industry-selected candidates receive fluid power “boot camp” training before working at the company location for the summer. To date, 59 students have participated in this program, with more than 75% going on to work in the fluid power industry. ƒƒ Fluid Power Courses. Fluid power lab exercises, textbook chapters, and online training developed by CCEFP professors are offered across the nationwide network of undergraduate mechanical engineering programs. ƒƒ National Fluid Power Engineering Challenge. Building on this success, we are now exploring support and expansion of a fluid power-themed national engineering challenge, to be conducted by teams of undergraduate engineers at our nation’s universities. Many of these competitions exist, and have become an engaging staple of the undergraduate engineering environment, giving students both exciting opportunities to explore and apply their developing skills and to connect with particular technologies and industries. For several years, NFPA member Parker Hannifin has sponsored and supported one of these competitions—the Chainless Challenge—and the NFPA and the CCEFP are now working in partnership with Parker to see how the program can be repositioned under an NFPA umbrella, allowing many more fluid power companies to get engaged. The goal would be to significantly raise the national profile of fluid power in these engineering universities and get hundreds more budding engineers engaged in our industry. The support and engagement of NFPA members is critical to our success in all of these areas—and several more that are Eric Lanke being discussed. To that end, we have recently launched three new Education Committees—one for each school type described in our ends statements—to help plug members into our existing and developing programs. Anyone interested in growing the fluid power workforce is invited to join the committee in a chosen area to help drive the programming even further.

Roger Betten,


Roger Betten is the current president of MFP Automation Engineering. He has nearly 30 years of fluid power experience with numerous technical certifications over the years, most recently the Certified Fluid Power Hydraulic Specialist (CFPHS) designation. His passions include his family, serving his customers, God, and hunting.

For me, fluid power runs in my blood. MFP will be a third-generation, family-owned company originally started by my family in 1991. My passion for the industry only grows as I see the exciting opportunities for expansion and how much more we are able to offer our customers. I’ve always been heavily interested in serving people and creating relationships. Working in fluid power has combined my love of manufacturing, engineering, fluid power, and unforgettable people, relationships, and customers. This industry is a perfect hybrid of all of those aspects. It allows me, my family, and the great employees at MFP to truly enjoy what we do every single day. As we look forward to celebrating the company’s 25th anniversary next year, it is especially exciting to see the success story the employees and customers have allowed us to create from a small manufacturing shop first located in Grandville, Mich.

How did you get started in the fluid power industry?

Becoming CFPHS certified through IFPS wasn’t an option. The knowledge gained through the IFPS creates a direct tie-in with serving our customers and better understanding this ever-changing industry. We are continually looking for opportunities to expand our knowledge within the fluid power industry and to become more credible. Becoming certified has allowed me, our engineering team, and technical sales team to keep a leg up on our competition, as well as obtain the most up-to-date information and knowledge the industry has to offer. The investment of obtaining this certification has proven invaluable. There seems to be a respect within the industry for those who see the significance in great organizations, such as the IFPS. As we grow and add employees, we will continue to add certification goals to our technical positions within MFP.

Why did you decide to pursue certification?

The experience was efficient and exceedingly worthwhile. I have already seen a return on my investment of time and energy to procure this certification. Upon registering for the certification, the organization was quick with communication to let me know how the upcoming process would be and what to expect. The study guides were a great reminder of the importance of continued learning. We preferred the one-week refresher training and then the official certification testing on the last day; this approach not only taught our team best practices, but also confirmed our company culture for continuous learning. The IFPS certification has taught me the importance of safety, education, and observing and maintaining skill levels of our employees. The certification was comprehensive and exemplified the importance of all facets and positions within our company. We not only have engineers on staff, but also sales specialists, technicians, and mechanics. The combined team effort and up-to-date knowledge is what keeps our company at the forefront of success.

How would you describe the certification process?

Being IFPS certified has assisted in numerous capacities. From building relationships to understanding fluid power systems design even better, the certification has reignited aspects of interest in the field for me. This certification program has become defensible to any issues that may arise in the principles and application through the industry and related challenges. The coursework was inspiring, practical, and has lent knowledge and understanding to real-life applications that we don’t always address in the moment. When others in the industry see the insignia of being CFPHS certified through IFPS, there is a deeper understanding and respect for the effort it took to obtain that certification. That alone has proven the value of IFPS.

How has certification helped your career?

“The better the individuals are trained, the better the industry is as a whole.” 20 • January/February 2016 •

Certification has allowed us to stay ahead of the competition by offering better solutions to our customers in situations where they are not just comparing the total quoted price. Certification allows us to enter conversations with fresh new technical ideas, and almost demands a level of respect for our solution and product presentations in today’s fast-paced world. We believe that staying on top of the certifications and promoting new employees to strive for this certification allows MFP to add a higher value to our customers by offering greater technical solutions that may not always be the most cost-effective solution up front but offer the highest payback for our customers in the long run.

How has certification changed the way MFP does business in terms of efficiency, reduced costs, etc.?

The fluid power industry is continually expanding and growing into the future and offering solutions to numerous other industries. Without the knowledge and certification that IFPS offers, students and the upcoming workforce could potentially miss out on some of the most valuable applications and education. The better the individuals are trained, the better the industry is as a whole. Missing out on this pertinent certification puts the industry in jeopardy of the great information and education potentially being overlooked.

Why is certification important to the fluid power industry?

What advice would you give to someone thinking about starting the IFPS certification process?

The course is valuable, comprehensive, and advanced. If interested in the certification, be prepared for an intense coursework and deeper understanding of the fluid power industry. The certification is as valuable as you allow it to be. I would recommend taking the course to anyone seriously invested in the industry. Certification provides time in class, on-site, and with real applications for an even deeper understanding of the material.

Where do you see the fluid power industry heading in the next 10 years?

With the advancement of technology and online marketing, I see the fluid power industry launching far into numerous other industries that may not even know they could have a great dependence on fluid power. Our company believes the more we can add on to a product and become an expert in turn-key solutions, the better suited we are for the future. Hiring on a team of electro-mechanical engineers for panel assembly has provided great success. The direct tie-in to becoming a one-stop shop for our customers has been invaluable. It saves the end-user time, money, and potential misunderstanding of the originally built system. These expertly crafted add-ons have added so much value, and that’s where we see the future of the fluid power industry heading.

THE PHOTO CONTEST Win Some Cash and Get Published!

The International Fluid Power Society (IFPS) has dedicated June 19 as “Fluid Power Professionals' Day” - a day of recognition for all of us who work in the fluid power field! It has been said that fluid power is a “hidden giant” because it is so common in every aspect of our day-to-day existence that we have simply overlooked the obvious. There is not a vehicle, ship, plane, or train that can operate without fluid power. There is no consumer item, no electronic gadget, and no morsel of food we grow that can exist in enough quantity at a cost we can afford without the use of fluid power and our efforts. From the ancient waterwheels of an emerging agrarian economy through the renaissance of industrial revolution to the automation and information technology age of today, we have worked to utilize, maintain, improve, and advance this all-encompassing technology. These efforts have improved productivity, ensured safety, and provided critical services that improve the quality of all of our lives. THANK YOU!

Why June 19th? A little bit of history behind the date is interesting. Blaise Pascal—a French mathematician, inventor, writer, and physicist—was born on this day clear back in 1623. His work in hydrodynamics and hydrostatics, including the invention of the hydraulic press, paved the way for all future innovations. He was also instrumental in experiments in pneumatics that examined the behavior of air in a vacuum and validated the work of the man who invented the barometer, Evangelista Torricelli. Because of Blaise Pascal and his work, the scientific foundation of thermodynamics and fluid power was set to build upon for those who followed.

The Fluid Power Professionals' Day Photo Contest had been a success since its beginning in 2014. We love seeing images of the industry at work and the professionals who keep it going. Have your camera handy to snap pictures that could belong in the following categories: • Fun with Fluid Power (geared towards youth) • Fluid Power Professionals in Action • Power Density • Fluid Power in Motion • People’s Choice Award (tell your friends and family to vote for your entry!)

Prizes for each category • • • •

1st place – $250 2nd place – $100 3rd place – $50 People’s Choice – $100

Winners will be published in the Fluid Power Journal. Contest runs from January 1st to March 31st, 2016. Visit www. to enter. • January/February 2016 •


You Can Influence the Fluid Power Industry with


Talking to others about oneself is natural. Explaining one’s career in fluid power to the Average Joe is often complex, and the conversation usually involves big hand gestures to describe the size and scope of your latest project, such as “Can’t believe we load-stabilized that fire truck before the 100-ft ladder was extended” while stretching your arms as wide as possible. I enjoy my career in fluid power, as I imagine you do. You wouldn’t have opened our industry’s magazine and started reading this article if you didn’t. So, based on our shared enjoyment of fluid power, allow me to propose some thoughts. Our industry’s employees are aging. We need new blood to pick up the fundamental knowledge we’ll soon lose. We can’t count on colleges, evidenced by the lack of courses available. It’s up to us to make changes or create influence. So how can you help? Think about that for a second. How can an individual “make changes or create influence” to an industry? I have an answer, but you’ll have to give something to make it work. A plan implemented by the IFPS Orlando, Fla., chapter has worked for nearly a decade, and it's got nothing to do with a mouse you visit on vacation. IFPS had at least 50 active local chapters, located all around the U.S. and a few internationally. I use the word “had” because chapters are past-tense in 2015. Meetings took place to allow discussion about the latest technology between professionals. Today, chapters don’t exist because you can chat online and download any literature you like. However, chapters can be refocused to facilitate this much-needed change and influence. Chapters need your time. That’s all you give. Funding comes from IFPS, and I can help you with two sheets of paper to secure it. Call some fluid power friends, set a meeting date, make promises of time that you can keep, and call me again. I’ll help you get in touch with kids where you live who are looking for opportunities to excel in STEM-related programs. You’ll use the funding as a donation to help these programs survive, and you’ll give your time to fluid power-related activity in those programs. You’ll do it with colleagues and you’ll inspire kids who would otherwise have no idea how that fire truck doesn’t topple over when the ladder swings to the side. This really is simple; it just requires a little time. By demonstrating the magic of fluid power, you'll help kids grow and consider this industry as a career path. My local chapter can help you with every step, from getting your chapter rebooted to recommending programs local to your city or state. I promise only one thing: what you and our industry get out of this effort will be worth more than what you put in. E-mail me when you’re ready to get started. Scott Gower, CFPS, is a member and past president of IFPS Chapter 49 in Orlando, Fla. He is northern district manager for Gulf Controls Co. Inc. Mr. Gower can be reached at

Gold Mine Crusher with Erratic Pressure

What could have caused the problem? SOL. 1A

A hydraulic power unit operating a rock-crushing machine had erratic pressure problems, causing the crusher to stall when the pressure seemed to relieve at a lower pressure than needed. The machine was over 30 years old and was somewhat quite simple in design. The circuit attached shows the main relief valve remotely controlled so the operator could reverse the motor’s rotation with the directional valve and adjust the pressure higher than normal to clear jambs. Once the jamb was cleared, he would reset the pressure back to the normal setting and shift the directional valve back to rotate the crusher motor in the normal operational direction. They determined that the remote control relief valve was worn badly and needed to be replaced. Their storeroom had the same brand of relief with the same spring range, but with just one letter difference in the model number. They installed it in the manifold, adjusted the valve from fully open to the number of turns closed used by the old, similar valve with the same spring rating, and then started the system up. It seemed to run fine until the crusher jammed and blew the side of the pump out. Luckily, no one got hurt.

Solution to Previous Problem



Inline & 90° Hydraulic Live Swivels • Rated To 10,000 P.S.I. • Heat Treated • Available in BSPP • Superior Quality Alloy Steel • Rebuildable Ball Bearing Design • Withstands Heavy Side Loads • 304 & 440 Stainless Steel • Full Flow — Low Pressure Drop Custom Design & Sizes Available

The D05 explosion-proof valve that was used on the Navy torpedo line had an air gap designed coil. This style of coil needs to fully shift for the high in-rush amps to drop to the low holding amps. This shouldn’t have been a problem, especially for new valves. However, because the cylinder has a rod to cap end area ratio of 2:1, the returning oil from the retracting cylinder would force 40+ gpm flow through the directional valve that's only rated for 26 gpm. Many valve spools will try to move to the center position when their maximum flow rate is exceeded. This will cause the air gap solenoid to move off of the fully shifted position, increasing the holding amps causing the coil to fail. The OEM replaced the D05 valve with a larger valve to solve the problem. The problem was printed in our November/ December 2015 issue. See it on our website, www.

aton sponsored the second-annual “Hydraulics are Fun!” event alongside Hennepin Technical College in Eden Prairie, Minn. The educational opportunity introduced 27 minority high school students to how hydraulics work in their everyday lives and how they can pursue hydraulics as a future career. The targeted students were identified through Cookie Cart, a non-profit organization that provides North Minnesota teenagers with work, life, and leadership skills through experience and training in an urban nonprofit bakery. To kick off the event, the students took a behind-the-scenes tour of Valley Fair amusement park to learn how hydraulics and engineering keeps rides operating safely. The students greatly enjoyed seeing the pumps in action at the amusement park, especially the hydraulic pump on the Thunder Canyon ride. “At Cookie Cart, we hope to give teens a positive learning environment, where they can gain the skills they need to expand their career options and live better lives,” said Matt Halley, executive director, Cookie Cart. “We were pleased by how engaged the students were in learning about their educational options, and we look forward to continuing this successful partnership with Eaton and Hennepin Technical College.” Following the tour, students headed to Hennepin Technical College, where they learned about career opportunities at Eaton

SCHUNK Participates in National and State Apprenticeship Week In a ceremony held in November, the NCTAP, Apprenticeship 2000, Apprenticeship Catawba, and Siemens Charlotte were all recognized by North Carolina’s Governor Pat McCrory and North Carolina Department of Commerce for leadership and mentoring of two new groups in Guilford and Alamance counties. SCHUNK is a partner in the NCTAP program, which is a four-year program based in North Carolina’s Triangle area and focuses on integrated basic training that develops technical, methodological, and social skills. The core training program gives apprentices an opportunity to develop a wide range of skills with a hands-on approach.

Jack Rensel, a second-year SCHUNK apprentice, spoke about how the program allowed him to “really understand the manufacturing environment and how everybody in the process comes together for a big picture.”

OIL AND WIND INDUSTRIES JOIN FORCES FOR NEW PROJECT The concept of using wind power for offshore and oil and gas applications is one step closer to realization with WIN WIN (WINd powered Water Injection), a DNV GL-led joint industry project (JIP). Project participants are ExxonMobil, ENI Norge, Nexen Petroleum UK Ltd., Statoil, VNG, PG Flow Solutions, and ORE Catapult. Initial DNV GL studies showed that a

standalone wind-powered water-injection system could become cost competitive for various types of applications, particularly for water injection far from the production platform and when costly retrofitting is not an option. DNV GL launched the WIN WIN JP to help develop the concept further. The project is now in the phase where the technical concept is being de-

veloped and the technical feasibility assessed in detail. Two of the main challenges being addressed are the off-grid operation of the system and the reservoir’s response to variable injection rates. Once these technical challenges are cleared, the concept’s economic viability will be analyzed using realistic cases provided by JIP partners. The JIP has been up and running since the beginning of 2015 and is scheduled for completion in the first quarter of 2016.

Ready-to-install servo-hydraulic axes have an integrated fluid loop and are driven by the same servo drives as the electro-mechanical versions.


nyone gaining only a superfluous familiarity with fluid technology can easily underestimate the performance and intelligence of modern hydraulics. Who would think that this technology is highly precise, energy efficient, and ready today for Industry 4.0 applications? Here are six capabilities of a strong drive technology:

MICROMETER PRECISION Electro-hydraulic axis controllers close the control loop decentrally, similar to electrical servo drives, and harmonize the target/actual position in real time within milliseconds. The precision of the movement solely depends on the respective utilized measuring system. In tool and plastic machines, hydraulic drives reliably position axes to a precision of a few micrometers.

COMPACT It is often difficult to place electromechanical drives with sufficient performance in tight construction spaces. Unlike hydraulic drives, they also add significant heat. Since power generation is decentralized in the power unit and since it is connected to the actuator via lines or pipes, OEMs can generate high forces even on minimal construction space. The relatively low level of heat created in the work area dissipates optimally through the hydraulic fluid.




Fluid technology is not always inherently linear. Drive software for hydraulic actuators takes these particularities into consideration and harmonizes them automatically. Preprogrammed, typical hydraulic functions, e.g. synchronization or positiondependent braking, merely require the optimization of parameters within the scope of startup. They are based on a transparent software structure and function equally on all hardware platforms.

Ready-to-install servo-hydraulic axes have an integrated fluid loop and are driven by the same servo drives as the electro-mechanical versions. Since axes are encapsulated systems, engineers must only connect power and communication cables for assembly and start-up, and then start-up can begin. Everything else (for example, the parameterization values determined from simulations) is already stored in the drive software and supports the plug and run philosophy.

Software combines the best from electrical and hydraulic systems. The decentralized intelligence in the electronic control device adjusts the rotational speed of the pump drive on demand as the consumer requires power, or it lowers it to zero. In comparison to common constant drives, this reduces the energy consumption of hydraulic power units by up to 80%. By the way, even older facilities and machines can be retrofitted without major efforts to significantly reduce the energy consumption in production.

OPEN AND OUTGOING With increasing frequency, realtime Ethernet protocols in modern machines integrate all actuators and peripherals into each other. Modern motion controls for hydraulic drives support all common protocols, e.g. Sercos, EtherCAT, Ethernet IP, PROFINET RT, Powerlink, and Varan. Their software is also based on open standards, e.g. IEC 61131-3 and PLCopen. This makes them an ideal match for the increasingly integrated and technologyoverlapping infrastructure of modern production environments – all the way up to Industry 4.0.


Scott Sardina,


Scott Sardina is a licensed professional engineer, certified fluid power hydraulic specialist, and engineering manager for Controlled Fluids, Inc. He previously held multiple engineering positions in the hydraulic systems division of The Oilgear Company for eight years. Scott has a Bachelor of Science degree in Engineering Mechanics and Astronautics and Mathematics from the University of Wisconsin. He also has a Master of Science degree in Engineering Mechanics. He has worked on various demanding applications for forging, extrusion, aerospace, civil, and oil and gas industries. He has worked in all aspects of the project phase from design to project and applications engineering. Scott now resides in Houston, Tex., and is dedicated to managing the engineering team at Controlled Fluids, Inc. He is a member of the 2015 IFPS Board of Directors.


How did you get started in the fluid power industry?

As like many others, I accidentally stumbled upon the fluid power industry. I started as an intern at Oilgear in Milwaukee, Wis., after my freshman year of college. My career started in the hydraulic systems division, which introduced me to many different applications. I enjoy working with hydraulics due to the tribal knowledge, variety of applications, and its necessity in industry.


What have you gained, professionally and personally, by being involved in the IFPS?


What have you learned so far by working in the fluid power industry?


Where do you see the fluid power industry heading in the next 10 years?


What advice would you give someone just starting out in the industry?

The fluid power industry truly is a niche market. There is an ever-growing need for people who understand hydraulics and how to properly apply it. Fluid power is all around us and affects our lives on a daily basis.

Depending on the application or industry, there will be an increased use of environmentally friendly fluids with a high demand on efficiency. Also, I foresee system pressure requirements going beyond the standard 3000 and 5000 psi, along with a need for more wireless control. Think of controlling a system wirelessly with your phone. Some manufacturers are starting to do this with their products installed in hard-to-reach areas.

I have three pieces of advice: ƒƒ Learn as much as you can from those before you, because a lot of the information cannot be found in a book. ƒƒ Figure out what you enjoy the most (systems, design, components, etc.) and become an expert in it. ƒƒ Get out in the shop or field, and turn a wrench.

My involvement with IFPS started with taking the Hydraulic Specialist certification exam. The more I learned about IFPS and its goals, the more I wanted to get involved. I’m a firm believer in educating people on fluid power, which is a large part of the organization. I was appointed to the IFPS Board of Directors in March 2015 and look forward to influencing the fluid power industry even further. Everyone in the organization is very passionate about what they do, which is great for the advancement of the organization and outreach of the industry.


What are some of your favorite hobbies or interests?

I enjoy training for marathons and triathlons in my free time. My ultimate goal is to run a marathon in every state. I have run eleven marathons and covered seven states. As for triathlon, I completed my second full Ironman in 2015 and have done multiple other triathlons in the past.



What is something people would be surprised to learn about you?

Why did you decide to pursue IFPS certification, and how has it helped your career?

I was first introduced to the IFPS certifications in 2013 when one of my colleagues at the time was unable to take the Hydraulic Specialist exam, which opened up a slot for me. I was asked a week prior to the exam if I was interested. After some research on IFPS, I accepted and was successful in obtaining the certification. The CFPHS certification has helped me stand out in the industry and demonstrate my dedication to fluid power.

I have been in twelve operas and considered majoring in vocal performance instead of engineering.

Utilization of Sensitive Compliant Lightweight

Today’s industrial robots are well-fitted for the needs of mass production. They can perform repetitive tasks with high performance within a well-structured environment. Their capability of dealing with process uncertainties or producing different products (or product variations), however, is limited. Therefore, the economically viable use of industrial robots outside mass production is also limited. Most of today’s standard robots require robot experts to program them. Especially in small and medium-sized enterprises (SMEs), those experts are regularly not available, posing yet another obstacle for

40 • January/February 2016 •

widespread robot deployment. To overcome these obstacles, the consortium of the research project SMErobotics1 is working on different aspects of the robot lifecycle with the vision of deploying cognitive robotic systems on SME shop floors. An integral part of the project is eight demonstrator setups, which are used to evaluate and optimize the research and technical developments based on realistic manufacturing conditions. Reference applications from different industrial sectors have been selected to cover a broad range of manufacturing scenarios and end-user needs.

 FIG. 1: Example of sectional valve components to be assembled within the prototype cell  FIG. 2: (opposite page) KUKA LBR iiwa robot utilized in the assembly cell

One of these demonstrators is the HyLight (short for hydraulic valve assembly using sensitive compliant lightweight robots) robot cell. This cell was developed by Brandenburg University of Technology, Chair of Automation Technology in cooperation with Bucher Hydraulics S.p.A. and Fondazione Democenter Sipe to cover the assembly of a family of sectional valves (Fig. 1) at the Bucher Hydraulics facility in Reggio Emilia, Italy. The targeted use-case is characterized by a large number of variations and small batch sizes for each respective variation. Therefore, a robotic work cell with a high degree of flexibility was needed. Fast changeover between different variations had to be possible, and new variations have to be teachable in an easy way. Additional difficulties arose from the assembly process itself: the insertion of the valve piston is difficult to realize with conventional industrial robots due to small cylindrical tolerances of the assembly components, which are below the robot’s positional accuracy. Also, the quality of the coupling between the piston and valve section has to be evaluated as part of the assembly sequence to avoid significant amounts of rework during subsequent manufacturing operations. The developed robot cell prototype is based upon the KUKA LBR iiwa lightweight robot (Fig. 2). Most industrial robots are programmed and controlled based on positions. Thus, the positional accuracy of the respective robot limits its applicability. The KUKA LBR iiwa is equipped with torque sensors on all of its joints. By comparing the measured with the expected torques (considering f.i. the current motion and load), external torques and forces (such as reaction forces during assembly operations) can be detected. Using a specific control mode (impedance control), the robot also is able to react to those forces and torques in specific ways—e.g., a virtual compliance can be assigned to certain axes or Cartesian motion directions. Other possibilities are to let the robot generate a defined contact force or force oscillation. These capabilities are used in the demonstrator cell to automate the challenging assembly steps of the targeted use-case. The most critical process (being the valve piston insertion) was solved using an oscillating motion of the robot’s end-effector in combination with a (program-wise) reduced Cartesian stiffness of the robot. Due to the reduced stiffness, the robot compensates positional and angular deviations, while the oscillating motion avoids jamming between the different edges on the piston and the valve section. After successfully assembling the piston, the robot performs a force-based quality check of the piston coupling, which is mimicking a currently performed manual quality check operation, but allows the definition of quality threshold values and the detailed documentation of this quality check. Only sections where the piston coupling meets specifications are assembled further. Possible malfunctions that can be detected using this test are that the piston cannot be shifted correctly within the valve section (due to a too-tight coupling) or that the valve section has impermissible leakage (due to a too-loose coupling).

 FIG. 3: (left) Loose supply of the assembly components (right) Components pre-separated by the robot  FIG. 4: (below) Validation of the assembly cell in the facilities of Bucher Hydraulics S.p.A., Reggio Emilia

In total, almost 20 different assembly operations have been realized. All of them have been packaged into separate functions of the robot cell. Utilizing these functions, the automatic generation of the assembly sequence for different valve section variations has been realized. The cell operator only has to load the production plan (including valve variations that have to be produced and the respective batch sizes) and has to ensure that all required assembly components are available in the work cell. The form of supply of the assembly components has been another important aspect during development of the prototype assembly cell. Due to cost and space constraints, a presorting of the different assembly components in matrizes or magazines is not possible. Instead, almost all components can be supplied loosely in small boxes, as it is the case for the current manual workstation. The robot then performs a pre-separation of the components and then grasps the pre-separated parts using a 2D-vision system (Fig. 3). The described assembly cell prototype has been set up at the Bucher Hydraulics facilities in Reggio Emilia (Fig. 4) and was deployed during several days of production in November 2015. During this period, the robustness of the individual assembly processes and the overall cell performance have been evaluated. Based on the experiences of this test-deployment, a modified version of the assembly cell will be developed by a robotics integrator.

Valve positioners have changed the way actuated control valves respond within a process control loop. By adding either a pneumatic or electro-pneumatic positioner to the valve, both single-acting and double-acting actuators can be precisely positioned and controlled. The valve can become an integral part of a digitally controlled system that relays both valve health and diagnostic information to assure that the loop maintains set point within a desired accuracy. This article details the many advantages of installing and applying a positioner to a basic, pneumatically actuated control valve package.


The operation of a control valve involves positioning its plug relative to the stationary seat within the valve. An actuator is directly coupled to the valve plug via the stem and moves the valve plug to the desired control position. A pneumatic or electric actuator is normally used to control this valve plug position. Pneumatically actuated control valves function either air-to-open or air-to-close. Air-to-open valves are normally held closed by a spring and require an air pressure to open; air-to-close valves are normally held open by a spring and require air pressure to close them. The mechanical design of the valve and actuator combination determines which way the actuator functions, but the desired fail-safe condition determines which type is applied (in case of plant instrument air failure). A computer, controller, PLC, thermostat, or other electrical-controlling device sends an analog electrical signal directly to an electric actuator or through a current/voltage-to-pneumatic converter or electro-pneumatic positioner to a pneumatic actuator. The signal is based

upon the desired system set point and modulates the valve linearly more open or more closed. By automating valves in this manner, they can be used to directly and/or indirectly control temperatures, pressures, and flows within an open or closed-loop system. Heat exchangers are a common type of closed-loop control application where both pneumatically and electrically actuated control valves can be used to regulate water, steam, and condensate. A partial graphical representation of a typical heat exchanger utilizing a control valve is shown in Fig. 1.


As modern heat exchange system design demands higher efficiencies, so has the need for improving control valve performance. Closely matching heat exchanger performance with process system demands while generating minimal waste adds up to real savings. The accurate modulation and control of valves that offer fast response and accuracies within 2% of set point adds up to less waste steam and condensate fall-out and removal. Some of the advantages of using valve positioners include the following features:


A heat exchanger that does not respond quickly enough to temperature changes brought on by process load changes/upsets to the steam system can be caused by something as simple as an incorrect hot water or steam valve or valve actuator being used. Everything from poor system or piping redesign to added demand caused by facility expansion can result in this slow response. Changing from an electrically actuated valve to a pneumatically actuated valve that utilizes a positioner can sometimes make the difference provided the

heat exchanger can still meet the facility’s capacity requirements. With the correctly sized pneumatic actuator, the valve reacts faster than its electrically actuated counterpart and can keep up with faster-changing hot water demand.


If higher differential pressures or varying differential pressures across the valve plug cause the valve position to change, the positioner automatically adjusts the air pressure to the actuator to “re-position” the plug according to the control signal. When a positioner is used, the valve has its own closed-loop control based upon the input signal and stem position feedback. This is accomplished through the stem position feedback linkage, pneumatic amplification relay, and adjustment of the output pressure to the actuator according to the input control signal. This closed-loop control circuit is integral to the positioner and therefore maintains consistent closing and opening forces (thrust) dictated by the differential and valve position.


Larger diaphragm or piston-actuated control valves can require increased air volumes, increased forward and reverse flows, and increased air pressures that are not generated by traditional converters (I/P or E/P). For example, a larger pneumatic diaphragm-style actuator may have an internal volume of 0.30 ft3 (cubic feet) that must be filled in order to move a valve fully to the open or closed position. If a positioner is used that has a forward and reverse flow rating of 0.07 scfs (standard cubic feet per second), that same valve will open or close within 4.3 seconds. Without the use of a positioner, the open or closing time can be very long. Most I/P and E/P converters are only rated for 0.02 scfs forward flow volumes and have reverse flow volumes of even less. So a valve may open within the required system response time but close at an unacceptable rate.

Positioners also supply air pressures to the actuator at or near their supply pressures to move the valve into the desired position. They become the “powering force” regardless of how much air pressure (psi) is required to the actuator in order to move the valve where it needs to be to achieve force-balance equilibrium. An I/P or E/P converter cannot and does not operate in this manner. The converter supplies an output pressure based upon the linear electrical control input signal only. Usually, their pressure spans are within 30 psi with normal operating ranges of 3-15, 3-27, or 6-30. Those air delivery pressures can only be changed by 2-3 psi. While the electro-pneumatic positioner may receive the same type of linear electrical control input signal, it is not bound by the calibrated operating range restrictions. It will deliver pressures all the way up to its regulated supply setting to the actuator. Being able to deliver these higher pressures is very helpful, especially in overcoming the negative effects of hysteresis and deadband that are always present within larger actuator and valve combinations. Friction is the most common contributor to these negative effects and is always in opposition to the air pressure generated from the control signal at dynamic conditions. The positioner is always comparing desired set point with the stem position and adjusting the air pressure to the actuator so that the friction effects are minimized.


The concept of control action is more easily understood by considering a pneumatically actuated control valve that is air-to-open with an electro-pneumatic positioner installed. With direct control action, as the electrical input signal to the positioner increases, so does the pneumatic output from the positioner to the actuator. The valve opens and modulates proportionally while flow through the valve increases or decreases accordingly. With reverse control action, as the electrical input signal to the positioner increases, the pneumatic output from the positioner to the actuator decreases. Sometimes system design changes due to piping


In order for a pneumatically actuated valve to interface with an electric control signal generated by a controlling device, there are three methods of controlling valve position: a current/voltageto-pneumatic converter (I/P or E/P), a converter and pneumatic positioner combination, or the electro-pneumatic valve positioner. Choosing a valve positioner for control offers several significant advantages over using a converter only. • January/February 2016 •


re-routing or logic control changes within the controller, computer, or DDC require a control valve to operate in this manner. While the use of a positioner cannot change the valve’s function, it can switch its control action from direct to reverse and vice versa.


Many domestic hot water heat exchangers have two control valves of different sizes installed on the same control loop to handle wide-ranging system flow demand changes. A split-range set-up of those valves is a common method of calibration and set-up where positioners make this possible. Their flexible span and zero adjustments allow a valve’s travel and stroke to be shifted around within its range. In normal operation, a control valve’s full stroke will follow the full span of the input control signal. For example, an electro-pneumatic positioner that accepts a 4 mA to 20 mA analog input current will normally stroke a control valve from 0% to 100% of its travel respectively. If the positioner is split-ranged, the valve will travel 0% to 100% with only a corresponding 4 mA to 12 mA input current. In both examples, the valve’s span is shifted in relation to the input current signal. Split-ranging the positioner as described above allows one (smaller) valve to control at lower system demand while the other (larger) valve controls when system demand is higher. Fig. 2 shows the relationship between the positioner input signal and valve travel when two control valve positioners are split-ranged. Notice that the second valve does not begin to open until the input signal to the positioner is at 50% of span.


Installed inherent flow characteristics (design characteristic) of a control valve are determined by the type of plug, seat, cage, etc. that are used. Sometimes that linearization of a non-linear flow characteristic is necessary so that the process valve gain is constant, regardless of the controller output. Changing or adjusting the flow profile is necessary to tighten control accuracy and improve performance. Depending on the design and type of positioner, linearization can be accomplished by switching a mechanical cam or by digitally/ electronically reprogramming a new performance curve into the positioner. Utilizing a positioner to change the inherent flow characteristic can be a more cost-effective solution than installing a new valve or changing out the valve trim.

Valve Travel








Positioner Input Signal

44 • January/February 2016 •


Reducing the amount of lift or limiting a valve’s travel is sometimes required in a control system for performance or safety reasons. Valves are sometimes mistakenly oversized, resulting in inefficient operation at the lower 5-10% of their travel. Similar to split-ranging the input signal to match the full stroke of the valve, as described in the previous section, the positioner’s pneumatic output signal can be compressed to match the full electrical signal input. This allows full input resolution of the control signal to be applied to the first 5-10% of the valve stroke. But there is a trade-off between a valve’s ability to respond to small control signal changes and having more input span resolution. Hysteresis and deadband effects are greatly amplified and can negatively affect control valve performance with such a high “turndown.” Operating a control valve in this manner should only be a temporary measure until an appropriately sized valve can be installed. Sometimes a valve’s travel or lift is limited for safety reasons or process protection. If the positioner’s set-up and calibration is changed for these reasons, the installation of a mechanical travel stop should immediately follow. Mechanically limiting the travel assures that the valve will not open beyond this point in the event of a positioner failure and does not cause an unsafe condition.


Microprocessor-based electro-pneumatic valve positioner designs have not only allowed manufacturers to move away from using mechanical cams for determining stroke (and flow) characteristics, but they have also offered the ability to embed significant intelligence and communications into the electronics. This can be very advantageous when interfacing the positioner to control systems that utilize digital communications, such as HART®, BACnet®, Modbus®, or LonWorks® protocols. Sensors within the positioner now provide information associated with valve stroke and thrust, output pressures to the actuator, enclosure temperature, valve seat/plug wear, and valve performance. Onboard diagnostics and alerts are commonplace within digital valve positioners along with historian data logging of abnormal valve performance events. But added intelligence does come with an added cost. Depending on the type of digital positioner selected, the added technological complexity can be intimidating. In order to take advantage of the additional information, sometimes operations, engineering, and maintenance personnel must become familiar with many more control parameters and process variables. Software utility applications that allow valve positioner interfacing to a central computerized control system or PC are the most common methods of monitoring and changing those parameters. Using a software utility can ease the complexity through its display of graphical views of valve parameters. The software helps the end user interactively set-up, tune, and maintain the control valve/positioner and save the configuration into a software file for later reference or download. The use of a valve positioner can solve simple and complex control valve problems along with offering significant performance and accuracy improvements to a control system.
