The MOOG Servo Valve D663-4007 is an electro-hydraulic conversion component that can transform small electrical signals into high-power hydraulic outputs. Its performance directly affects the operation of the electro-hydraulic control system, making it a key and core element of the entire system. Understanding the working principle of the MOOG Servo Valve D663-4007 is essential for the correct use of the electro-hydraulic control system.
Working Principle of the MOOG Servo Valve
The MOOG Servo Valve D663-4007 achieves closed-loop control of the valve core displacement through an integrated circuit board that includes a position sensor and a linear force motor. The electrical signal corresponding to the desired valve core displacement is input into the integrated circuit board, where it is converted into PWM current to drive the linear force motor. An oscillator excites the position sensor to generate an electrical signal proportional to the valve core displacement.
