Electrohydraulic servo valve - Wikipedia

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 electrical signal. Servo valves can provide precise control of position, velocity, pressure, and force with good post movement damping characteristics.

Troubleshooting Of Servo Valve All About Circuits

Mar 07, 2019 The servo valve does not require that much drive current and so this could be the entire thing. Lots of symbols that I am not familiar with, though. Servo valves mostly need an amplifier when there is a feedback system in place. The feedback signal would come from either a pressure sensor, a load cell, or a position sensor, possibly a LVDT.
