Valves & Actuators

Devices that direct, regulate or control liquid flow by opening, closing or partially obstructing various passageways, valves are often classified by their means of actuation — hydraulic, pneumatic, manual, solenoid and motor. Actuators are a kind of transducer, typically transforming an input signal into motion and thereby controlling valve position.
