Product details: G771K208A MOOG electro-hydraulic servo valve

The working principle of G771K208A MOOG electro-hydraulic servo valve is based on the electro-hydraulic servo system, which mainly consists of key components such as permanent magnet torque motor, nozzle, baffle, valve core, valve sleeve, and control chamber. When current is applied to the input coil, the permanent magnet torque motor generates a torque that moves the baffle to the right. The movement of the baffle will change the gap between the nozzle and the baffle, thereby affecting the throttling effect of the nozzle. Specifically, when the baffle moves to the right, the throttling effect of the right nozzle is strengthened, the flow rate decreases, and the back pressure on the right side increases; At the same time, the throttling effect of the left nozzle decreases, the flow rate increases, and the left back pressure decreases. This change in back pressure on both sides can cause the force at both ends of the valve core to lose balance, resulting in the valve core moving to the left. The movement of the valve core will change the channel of high-pressure oil, thereby controlling the flow rate to the load. At the same time, the load return oil flows through another channel through the return port and enters the oil tank, forming a complete hydraulic cycle. In this process, the displacement of the valve core is proportional to the input current of the torque motor, and the hydraulic pressure acting on the valve core is balanced with the spring force. Therefore, in the equilibrium state, the differential current of the torque motor is proportional to the displacement of the spool. If the input current is reversed, the flow rate is also reversed, thus achieving precise control of the hydraulic system.
