The jet-pipe servo valve has strong pollution resistance, and in particular has the unique ability of 'failure → return to zero' and 'fault → safe', which is widely used in actuator hydraulic power control of various aircraft. Almost all passenger planes and fighters use the jet-pipe servo valve.
Jul 31, 2017· A servo valve is a precisely machined spool-type directional control valve with a current-driven mechanism using a torque motor to control the spool position. A torque motor can be considered as an electromechanical transducer that produces a small deflection proportional to the input current.

The word "hydraulics" is based on the Greek word for water and originally meant the study of the physical behavior of water at rest and in motion. Hydraulic systems in aircraft provide a means for the operation of aircraft components. The operation of landing gear, flaps, flight control surfaces, and brakes is largely accomplished with hydraulic power systems.

Jul 18, 2018· Learn how hydraulic proportional and servo valves work. Understand the different types of valve that are available, their function and where they are used.
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.
