   en.wikipedia.org/wiki/Flow_control_valve

   Control valves are normally fitted with actuators and positioners. Pneumatically-actuated globe valves and diaphragm valves are widely used for control purposes in many industries, although quarter-turn types such as (modified) ball and butterfly valves are also used. Control valves can also work with hydraulic actuators (also known as ...

6. Valve actuator - Wikipedia

   en.wikipedia.org/wiki/Valve_actuator

   Air (or other gas) pressure is the power source for pneumatic valve actuators. [1] They are used on linear or quarter-turn valves. Air pressure acts on a piston or bellows diaphragm creating linear force on a valve stem. Alternatively, a quarter-turn vane-type actuator produces torque to provide rotary motion to operate a quarter-turn valve.
