Moog 312A6077P001 Servo Valve

Moog 312A6077P001 servo valve is a high-performance servo valve produced by Moog. The following is an introduction to it:

Working principle

Moog servo valve is generally composed of a permanent magnet torque motor, a nozzle, a baffle, a valve core, a valve sleeve and a control chamber. When current passes through the electromagnet, an electromagnetic force is generated, causing the armature of the permanent magnet torque motor to drive the baffle to move, changing the gap between the nozzle and the baffle, and then changing the pressure in the nozzle chamber, pushing the valve core to move. The movement of the valve core controls the flow of the fluid and realizes the control of parameters such as flow and pressure. At the same time, the position signal of the valve core is fed back to the input end through the feedback loop, and compared with the input signal to form a closed-loop control, thereby achieving more accurate control.
