USA MOOG pressure and flow (p/Q) control valve

USA c consists of a permanent magnet torque motor, nozzle, baffle, valve core, valve sleeve, and control chamber (see figure). When the input coil is energized by the servo valve, the baffle moves to the right, strengthening the throttling effect of the right nozzle, reducing the flow rate, and increasing the back pressure on the right side; simultaneously, it reduces the throttling effect of the left nozzle, increasing the flow rate, 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. The load return oil flows through C1 and the return port, entering the oil tank. 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 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.

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

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