WebHow Does A Hydraulic Servo Valve Work? (Complete Answer) A pressure control valve can be used to control the pressure in a circuit. The force can be measured by a load cell or a pressure transducer. The feedback signal from the sensor is analyzed and converted into an electrical signal that is sent to the control circuit. A servo valve receives pressurized hydraulic fluid from a source, typically a hydraulic pump. It then transfers the fluid to a hydraulic cylinder in a closely controlled manner. Typically, the valve will move the spool proportionnaly to an electrical signal that it receives, indirectly controlling flow rate. See more An electrohydraulic servo valve (EHSV) is an electrically-operated valve that controls how hydraulic fluid is sent to an actuator. Servo valves are often used to control powerful hydraulic cylinders with a very small See more Types Electrohydraulic servo valves may consist of one or more stages.
