Easy mounting IML lock eases maintenance of valves and actuators

Smith Flow Control (SFC) has introduced its ISO-pattern IML intermediate lock with universal mounting. The IML lock uses an operating key to lock the actuator in an open or closed position so that the valve cannot turn – no matter what. No custom brackets are required; any valve or actuator with ISO standard mountings is compatible with the IML lock.

New interlocks safeguard against improper PIG process execution

The process of loading and unloading pipeline inspection gauge (PIG) launchers and receivers can have catastrophic consequences if performed incorrectly. A specific sequence of valves must be operated, pressurizing and depressurizing the PIG chamber in the same order every time, to avoid damage to equipment and injury to personnel.   

Easi-Drive provides safe, cost effective operation of multiple valves

The Easi-Drive portable valve actuator provides a safe means of valve actuation in hazardous areas. With the Easi-Drive, numerous valves in oil refineries and chemical plants can be operated by a single worker, without multiple dedicated valve actuators.

VALVE INTERLOCKS

The new QL and GL mechanical valve interlocks ensure potentially hazardous valve operations are performed in the correct sequence, eliminating the possibility of operator error or deliberate sabotage. They can be integrated with any size of ball, plug, gate, butterfly and globe valve. Mechanical interlocks are typically used to support “Permit to Work” procedures such as safety relief valve changeover, pig trap loading and retrieval, or filter changeover.
