MOV types?/motor operated valve

[alhnaity]

what MOV means exactly, is the actuator type always electrical? or we can call the valve actuated with fluid power actuator MOV also?

 

[LittleInch]

The M means motor, usually taken as electric, but any fluid powered MOTOR could be used. These are normally taken to be on, off, fail in position valves

A piston type actuator would normally be referred to as an XV.

In Oil & Gas we include pneumatically operated valves in the MOV category. Not sure it makes sense, but so many conventions don't. Valves with electrical actuators (generally not solenoids, but sometimes them too) are usually called MOV. Valves with hydraulic motors are almost always called MOV (even when the function is XV). Then it gets weird because both hydraulic and pneumatic linear operators are often referred to as MOV even though they are rarely fail-as-is valves and are often throttled.
