Lock Valve Function

Lock Valve Function. A function that adjusts the internal pressure of the tank to be equivalent to atmospheric pressure during negative and positive pressures. In an airlock valve, air is sealed (locked) between the inlet and outlet ports.

Locked Open (LO) and Locked Closed (LC) Valves from instrumentationtools.com

It may also provide stability, guiding, balance, and alignment, and facilitate assembly When the signal is present, the lockup valve is open and allows the free flow of compressed air from the positioner to. We need to perfectly isolate the equipment because fluids are very flammable or toxic so leakage of fluid can cause a huge problem.

Lockup valves are used as an accessory to modulating pneumatic actuators when it is functionally desirable for them to “fail in place” or “fail last position”. Air lock is used when it is required to automatically hold the air pressure in control valve diaphragm chamber of the actuator, in an event of failure of air supply.
