EW Series (Designs EWD/EWS/EWT) Sliding-Stem Control Valves through 10 x 8- & 12 x 8-Inch Sizes Design EW Description The EW Series easy-e valves (figures 1 through 5) feature large internal cavities with expanded end connections and a variety of unbalanced and balanced plug designs. Sizes available from 4 x 2(1) through 12 x 8 inches include 8 x 6 with 10-inch ends and 10 x 8 inch sizes. These combinations provide good fluid control in economical, high-capacity valve bodies that keep valve outlet velocities within practical limits.

These valves meet a variety of service requirements, such as power plants where oversized piping is used to limit fluid flow velocity. They also perform well in noise abatement applications; for example, high-pressure gas reducing stations where sonic velocities are often encountered at the outlet of conventional valve bodies.

The easy-e Valve Family EW Series valves are part of the versatile easy-e family of industrial control valves from Fisher Controls. easy-e valves share the following characteristics: Multiple trim material choices

Interchangeable, restricted-capacity trims and full-size trims to match variable process flow demands Different cage/plug styles that provide particular flow characteristics for highly-specialized applications.

The standard cage comes in three different flow characteristics: quick-opening linear equal percentage 1. Valve body size: end connection size by nominal trim size. For example, a 4 x 2 inch Design EWD valve has 4-inch end connections with nominal 2-inch trim.

1. The pressure/temperature limits in this bulletin and any applicable standard or code limitation should not be exceeded.

2. For temperatures above 450_F (232_C), a buttwelding-end CF8M (316 stainless steel) valve body with a Class 600 pressure/temperature rating must be derated; contact your Fisher Con trols sales office or sales representative for details. Since ANSI standards do not allow use of intermediate ratings for flanged valve bodies, a Class 600 flanged-end CF8M valve body with B7 bolting must be limited either to 450_F (232_C) or to inlet pressures consistent with Class 300 ratings.

3. Only 12 x 8-in. Class 900 valve bodies with threaded (-1) seat rings can take full Class 900 pressure drops; Class 900 valve bodies with clamped (no dash number) seat rings arelimited to Class 600 pressure drops. Also, there are two different 8 x 6-in. Class 900 valve bodies, one for use only with Cavitrol III cages and the other for use with all other constructions. An 8 x 6-in. Class 900 valve body with Cavitrol III cage can take full Class 900 pressure drops. For information on other 8 x 6-in. constructions that can take full Class 900 pressure drops, contact your Fisher Controls sales office or sales representative. All other 8 x 6-in. constructions are limited to Class 600 pressure drops (1440 psid flowing drop) even though installed in a Class 900 valve body.

PTFE Packing Systems: Packing Ring and Lower Wiper: PTFE V-ring(3) 1. Refer to the valve specifications in this bulletin for pressure/temperature limits of valve parts. Do not exceed the pressure/temperature rating of the valve. Do not exceed any applicable code or standard limitation.

2. The Environmental Protection Agency (EPA) has set a limit of 500 parts per million (ppm) for fugitive emissions from a valve in selected VOC (Volatile Organic Compound) services.

3. In vacuum service, it is not necessary to reverse the ENVIRO-SEAL PTFE packing rings.

The temperature limits of Design EWT valves can be extended above 450_F (232_C) by using PEEK (PolyEtherEtherKetone) anti-extrusion rings in combination with a spring-loaded PTFE seal. The PEEK anti-extrusion rings expand to close off the clearance gap between the plug and the cage where the PTFE seal may extrude at high temperatures and pressures. The temperature limits are extended to 600_F (316_C) for non–oxidizing service and to 500_F (260_C) for oxidizing service.

NOTE: EWN Series valves with Whisper Trim III cages are covered in a separate bulletin.

Features D Compliance with the Clean Air Act—Patented ENVIRO-SEAL packing systems provide a superior stem seal to help prevent the loss of valuable or hazardous process fluid. The ENVIRO-SEAL packing systems feature PTFE or graphite packing with live-loading for reduced packing maintenance.

D Noise Attenuation—In an EW Series valve, noise produced by high flow rates and large pressure drops can be reduced by up to 18 dbA with a Whisper Trim I cage and by up to 30 dbA with a Whisper Trim III cage.

Bulletin 51.1:EW Piping Economy—Expanded end connections of EW Series valve bodies may reduce the need for line swages while accommodating oversized piping arrangements used to limit fluid flow velocities.

Temperature Compensation—On designs with the seat ring threaded into the valve body (figure 5), the hung cage feature helps reduce gasketing problems caused by thermal expansion and contraction of long parts, such as the cage assembly.

Standard Trim Parts across the easy-e product line—Included are FGM gaskets, packing flange, studs, and nuts.

High-Temperature, Class IV or Class V Shutoff—Optional multiple piston rings (figure 14) for Design EWD and EWD-1 valve bodies permit Class IV shutoff up to 1100 F (593 C).

Use of C-seal trim (see figure 6) permits Class V shutoff up to 1100 F (593 C).

Increased Pressure/Temperature Ratings—12 x 8 inch Class 900 EW Series valve bodies with buttwelding end connections are capable of increased ANSI ratings called Intermediate Standard Ratings.

The extra strength of the valve body allows these valves to be used where pressures and temperatures exceed Standard Class ratings in ASME B16.34.

See Bulletin 59.1:027, Increased Pressure/Temperature Ratings for EW Series Steel Valve Bodies, for further information.

Sour Gas Service Capability—Optional special trim and bolting materials are available for applications handling sour fluids and gases. These constructions comply with the recommendations of the National Association of Corrosion Engineers (NACE) MR0175.

Because of the care exercised by Fisher Controls in procurement and manufacturing, additional testing and documentation to assure compliance with the NACE standard is not required, in most cases.

C-seal Trim Description C-seal trim (figure 6) is available for valves with port diameters from 2-7/8 inches through 8 inches.

With C-seal trim, a balanced valve can achieve hightemperature, Class V shutoff. Because the C-seal plug seal is formed from metal (N07718 nickel alloy, Inconel 718) rather than an elastomer, a valve equipped with the C-seal trim can be applied in processes with a fluid temperature of up to 1100 F (593 C).

These systems help you seal your process to conserve valuable process fluid and to protect the environment against the emission of toxic or polluting fluids. The long-life and reliability of these systems also reduce your maintenance cost and downtime.

For applications requiring compliance with environmental protection regulations, Fisher Controls offers the unique ENVIRO-SEAL packing system and, for toxic or lethal service, the ENVIRO-SEAL bellows seal bonnet (figure 19). The patented emission control packing system or seal bonnet keeps emission concentrations below the EPA 500 ppm requirement.

For a superior stem seal in applications that are not environmentally-sensitive, Fisher Controls offers the HIGH-SEAL graphite packing system. The HIGH-SEAL packing system provides superior sealing at pressure/temperature ratings beyond ENVIRO-SEAL limits.

ENVIRO-SEAL packing systems, available with PTFE, graphite, or Duplex packing, and the HIGH-SEAL graphite packing system feature live-loading and unique packing-ring arrangements for long-term, consistent sealing performance.

NACE Standard MR0175 Compliance Standard procurement procedures and manufacturing processes used by Fisher Controls assure that control valves with sour service trims comply with the chemical and physical requirements of NACE standard MR0175. Incoming raw materials are selected for sour service trims by specifications covering chemical composition, forming, hardness, heat treatment, and finish.

In addition, the subsequent machining, welding, and heat treatment of the materials being processed into finished parts is strictly regulated by manufacturing standards.

Because of strict start-to-finish manufacturing quality management, Fisher Controls offers a high degree of confidence that the parts and assemblies provided for sour service comply with MR0175. Additional testing and documentation to assure compliance with MR0175 is not necessary, in most cases. However, in cases where documentation is required, the following items can be provided: hardness test data

ENVIRO-SEAL and HIGH-SEAL Packing Systems

certificate of compliance to specification

The ENVIRO-SEAL and HIGH-SEAL packing systems (figure 18) from Fisher Controls offer exceptional sealing capabilities. These systems easily install in your existing valves or can be purchased with new valves.

Installation Unless limited by seismic criteria, the valve body can be installed in any position (as long as sufficient support is provided if a fabricated extension bonnet is used). However, the normal method is with the actuator vertical above the valve, since nonvertical positions may cause uneven trim wear and decreased trim life.

Flow through the valve body must be in the direction indicated by the flow direction arrow on the valve body. Consider installing an upstream strainer, especially if the valve body includes slotted or multihole Whisper Trim or Cavitrol cages.

Dimensions are shown in figure 20.

1. May be used down to –425 F (–254 C) if manufacturing process includes Charpy impact test.

2. This minimum is due to thermal expansion differential between piston ring and cage at low temperatures.

3. For high-temperature air, hydrocarbons, and certain other chemicals and solvents, but cannot be used with ammonia, steam, or hot water.

4. Has excellent moisture resistance to hot water and steam and may be used with most fire-resistant hydraulic oils, but cannot be used with petroleum-based fluids and other hydrocarbons.

5. Cannot be used with fire-resistant hydraulic oils.

6. May be used to increase hot water service capability to 450 F (232 C).

7. This material may be used for cyclic temperatures or those above 450 F (232 C).

8. Spring is used only with single PTFE V–ring packing; lantern ring replaces spring in other packings.

9. Except 700 F (371 C) on oxidizing service.

10. If used with PEEK anti-extrusion rings, PTFE/carbon seal ring may be used in temperatures up to 600 F (316 C) for non-oxidizing service or up to 500 F (260 C) for oxidizing service.

11. These materials not limiting factors.
