About Electrohydraulic Valve Actuators and Hydraulic Valve Actuators
Electrohydraulic valve actuators and hydraulic valve actuators convert fluid pressure into motion in response to a signal. They use an outside power source and receive signals that are measured in amperes, volts, or pressure. Some electrohydraulic valve actuators and hydraulic valve actuators move rotary motion valves such as ball, plug, and butterfly valves through a quarter-turn or more from open to close. Other valve actuators move linear valves such as gate, globe, diaphragm, and pinch valves by sliding a stem that controls the closure element. Throttling valves can be moved to any position, including fully open or fully closed, within the stroke of the valve. Typically, valve actuators are added to throttling valves as part of a control loop that includes a sensing device and circuitry.
