A history of care and innovation Sofis was formed in 2016 through the merger of industry leaders

Sofis: 40 years of innovation and global impact

Smith Flow Control and Netherlocks Safety Systems.

In 1985, Smith Flow Control was the first company to introduce the coded card linear key concept to valve captive key locking, a concept established across the industry today, to implement a safe sequence of operation in any process activity, protecting plants, the surrounding community, and the environment. Other innovations quickly followed, such as the Sequence Control Unit and the Pigging Control Panel. In 1993, Netherlocks Safety Systems introduced its own valve captive key lock product range, along with innovative complementary products that were introduced over the years, including the Actuator Switch Lock Panel and the PLC Controlled Key Cabinet for captive key locks.

The introduction of the Power Wrench, EasiDrive Portable Actuators and the VPI position indicator underlined the position of both companies as valve operation specialists, merging in 2016 to become Sofis, the global market leader today.

40 years ago, on April 10th, 1985, Smith Flow Control was founded in the UK. It later merged with Netherlocks, forming Sofis BV with Headquarters in the Netherlands. On that day, our inventors laid the foundation by introducing the groundbreaking coded card linear-key concept, which revolutionized valve interlocking technology. Today, this innovation is an industry standard, with over 450,000 linear key valve interlocks installed worldwide.

PORTABLE AND REMOTE VALVE ACTUATORS

FlexiDrive remote operator Safely operate inaccessible, hard-to-reach manual valves

The FlexiDrive remote operator provides safe control of hard-to-reach valves.

By positioning the operator station away from the valve, you can operate valves that are overhead, underground, submerged, enclosed, or in tight spaces.

Safe and accessible valve operation • Operate manual valves from an accessible location • Avoid confined spaces, hazardous areas, and difficult access points • Reduce the risk of workplace injuries

Protect operators from hazards • Keep personnel away from leaks, steam, and radiation

Eliminate extra equipment and cost

• Reduce exposure to heat and dangerous conditions • Maintain safety compliance with remote operation

• No need for scaffolding, lifts, or ladders • Avoid expensive dedicated actuators and infrastructure • Lower maintenance costs with a simple solution

An operator station sits up to 100 feet away from your valve

A valve station is fitted to your valve via a custom anchor and adaptor

Torque is transmitted through a cable to drive your valve

Manual valve captive key locks Protect your operators, your equipment, and your plant Sofis provides Netherlocks and Smith captive key lock solutions to eliminate operator error and ensure safe, uninterrupted plant operations.

Captive key locking with physical keys Captive key locks ensure manual operations follow the correct sequence, preventing errors and accidents by physically controlling valve and equipment movement with captive key technology.

Captive key locks can be added to all type of valves, independent from manufacturer, size, and pressure class.

Why choose coded key captive key locks?

• Fail-proof safety Mechanical captive key locking quantifies reliability and adds two independent protection layers • No power required No risk of electrical failures or software malfunctions

• Custom-engineered for any process Designed to fit your specific valves, equipment, and safety protocols

Common applications • Pressure safety valves (PSV) Guarantee one relief valve is open • Pigging Only open pig trap door when vessel is depressurised • Heat exchangers Ensure one exchanger is always online • Pump start Prevent dead headding of the pump • Product integrity Prevent cross-contamination

How it works Step-by-step control – Equipment stays locked until the correct key is inserted, ensuring each step happens in the right order. Valve can only be operated if both keys are inserted.

Unique coded keys – Each key is custom-coded to fit only the designated captive key lock, preventing unauthorized operation. And the use of keys across other systems nearby.

No bypassing, no mistakes – Operators cannot skip steps or override safety procedures, guaranteeing compliance.

Follow the steps below to isolate PSV A to take PSV A out for maintenance. PSV A is in process with V2 and V3 open, and PSV B starts in standby mode with closed inlet V1 and open outlet V4.

Step 4: Insert green key 3 into V3 and operate until fully closed. Remove red key 4 and return to cabinet.

Step 1: Retrieve green key 1 from the key cabinet and insert into closed V1.

With both keys inserted, the valve is unlocked and can be operated.

Step 3: Insert the yellow key 2 into V2 and operate until fully closed. Remove the green key 3 and bring to V3.

Step 2: Operate V1. When V1 is fully open, the yellow key 2 will be released and move to valve V2. The valve is locked in open position. Remove and bring to V2.

Key 4 returns to the control room, indicating that PSV A is fully isolated and can be taken out for maintenance. Following the captive key lock process prevents the isolation of the equipment by ensuring V1 is open and PSV B is online before isolating PSV A. Captive key locking and overpressure protection of the outlet valve by closing the inlet valve first. Eliminating the risk for an overpressure incident from isolated PSVs. 9
