MOOGHydraulic servo valve mainly refers to electro-hydraulic servo valve, which, after receiving electrical analog signals, outputs modulated flow and pressure accordingly. It is both an electro-hydraulic conversion component and a power amplification component, capable of converting low-power weak electrical input signals into high-power hydraulic energy (flow and pressure) output. In the electro-hydraulic servo system, it connects the electrical part with the hydraulic part to achieve the conversion of electro-hydraulic signals and hydraulic amplification. The electro-hydraulic servo valve is the core of the electro-hydraulic servo system control.
　　MOOGHydraulic servo valve is an actuator that converts electrical signal input into high-power pressure or flow pressure signal output in a servo system. It is an electro-hydraulic conversion and power amplification component. Servo valves have high sensitivity and good speed, and can convert small electrical signals (such as 10 milliamps) into large hydraulic power (such as tens of horsepower or more), which can drive various types of loads. In the past, hydraulic amplification devices such as nozzle baffle valves, jet pipes, or slide valve servo motors were included in the scope of servo valves. Since the 1970s, servo valves generally only refer to electro-hydraulic servo valves.

The principle and schematic diagram of MOOG servo valve. As for the valve itself, in general, its insensitivity to oil pollution is: high flow valves are better than low flow valves (under the same structural form and amplification stage), dynamic coil force motors (with high thrust or torque) are better than dynamic iron torque motors, slide valve type (with a larger flow channel after removing the fixed orifice) and jet tube type (with a larger distance between the nozzle and the receiving hole) are better than nozzle baffle type, proportional valves (with a larger slide valve stroke xv) are better than servo valves, and proportional pressure valves or proportional disassembly valves are better than proportional directional valves. For example, for nozzle baffle servo valves, the accuracy requirement for oil is better than level 6 of NAS1638 standard (level 14/11 of ISO4406 standard), while for dynamic coil force motor servo valves or proportional directional valves, the accuracy requirement for oil is only level 7 of NAS1638 standard (level 15/12 of ISO4406 standard). The precision requirements for oil for proportional pressure valves or proportional disassembly valves can be lowered by another level, such as level 8 of NAS1638 standard (level 16/13 of ISO standard), which is close to the oil usage requirements of ordinary drag systems.

MOOGServo valves are mainly used as actuating components in electro-hydraulic servo systems (see hydraulic servo systems). In servo systems, hydraulic actuators have the characteristics of good speed, high output power per unit weight, smooth transmission, and strong anti-interference ability compared to electrical and pneumatic actuators. On the other hand, electrical components are often used in servo systems to transmit signals and correct characteristics. Therefore, modern high-performance servo systems also use electro-hydraulic methods, and servo valves are essential components of such systems.
