Compared to other brands of servo valves, MOOG servo valves offer advantages such as energy saving, zero pollution, strong environmental adaptability, quiet operation, durability, and minimal maintenance, making them suitable for industries with high requirements for energy efficiency, performance, and environmental friendliness.

MOOG servo valves are primarily used as actuators in electro-hydraulic servo systems (see Hydraulic Servo Systems). In servo systems, hydraulic actuators, compared to electro- and pneumatic actuators, offer advantages such as faster response, higher power output per unit weight, smoother transmission, and stronger anti-interference capabilities. On the other hand, electrical components are frequently used in servo systems for signal transmission and characteristic correction. Therefore, modern high-performance servo systems also employ electro-hydraulic methods, and servo valves are essential components of such systems.

MOOG servo valves primarily refer to electro-hydraulic servo valves. Upon receiving an electrical analog signal, they output modulated flow and pressure. They are both electro-hydraulic conversion elements and power amplification elements, capable of converting low-power, weak electrical input signals into high-power hydraulic energy (flow and pressure) output.

MOOG Servo Valve Working Principle

The MOOG servo valve consists of a permanent magnet torque motor, nozzle, baffle, valve core, valve sleeve, and control chamber. When current is applied to the input coil, the baffle moves to the right, strengthening the throttling effect of the right nozzle, reducing flow, and increasing the back pressure on the right side; simultaneously, it reduces the throttling effect of the left nozzle, increasing flow and decreasing the back pressure on the left side. The forces at both ends of the valve core become unbalanced, causing the valve core to move to the left. High-pressure oil flows from S to C2, delivering it to the load. Load return oil flows through C1 through the return port and enters the oil tank. The displacement of the valve core is proportional to the input current of the torque motor. The hydraulic pressure acting on the valve core is balanced by the spring force. Therefore, in a balanced state, the differential current of the torque motor is proportional to the displacement of the valve core. If the input current is reversed, the flow rate is also reversed. The table shows the classification of servo valves.

The MOOG servo valve is a key component in electro-hydraulic servo control developed by MOOG Corporation. It is a hydraulic control valve that receives analog electrical signals and outputs modulated flow and pressure accordingly. Electro-hydraulic servo valves have advantages such as fast dynamic response, high control accuracy, and long service life, and are widely used in electro-hydraulic servo control systems in aviation, aerospace, shipbuilding, metallurgy, chemical and other fields.
