Hydraulic Hydraulic actuators use oil under high pressure as energy power source. Main features of hydraulic actuators are: Compact and small design Smooth operation over complete valve stroke Spring return actuators for fail-safe operation Possibility for submerged or sub-sea operation Hydraulic actuators can be equipped with many ancillaries such as: Limit switches (direct mounted to actuator or in a switchbox) Solenoid valves Throttle block Potentiometer Pilot operated check valves Lever or hand pump unit Function: Remote open/close position monitoring of the valve (mechanical switches or inductive proximity sensors) Remote on/off operation of actuator Speed control for increased operating times Continuous valve disc position feedback (resistance signal) Maintain valve disc position after hydraulic supply failure Manual override of operation after hydraulic supply failure Specific technical information on request.
