A MOOG Electro-Hydraulic Servo Valve is an electro-hydraulic conversion and power amplifiion component. Its primary function is to receive analog electrical control signals and then proportionally adjust the output flow and pressure of hydraulic fluid based on these signals, thereby achieving precise control of hydraulic actuators.
