Electro-hydraulic servo valve has many advantages, such as fast dynamic response, high control precision and long service life. It has been widely used in the electro-hydraulic servo control system in the fields of aviation, space, ship, metallurgy, chemical industry and so on.
The typical servo valve consists of permanent magnet torque motor, nozzle, baffle, valve core, valve sleeve and control chamber. When the input coil enters the current servo valve, the gear plate moves to the right to increase the throttle effect of the right nozzle, reduce the flow rate, increase the right back pressure, reduce the throttle effect of the left nozzles, increase the flow rate, and decrease the left back pressure. The force at both ends of the spool is out of balance, and the spool moves to the left. The high pressure oil flows from S to C2 and sent to the load. The load return oil flows through the C1 to the oil tank and enters the fuel tank. The displacement of the valve core is proportional to the input current of the torque motor, and the fluid pressure acting on the valve core is balanced with the spring force, so the differential current of the torque motor is proportional to the displacement of the valve core in the balance state. If the input current is reversed, the flow will also be reversed.
