The servo valve J761-003 is used in the electro-hydraulic servo automatic control system. Its function is to convert low-power electrical signals into high-power hydraulic output, which is a power amplifier element. It completes the automatic control of mechanical equipment through hydraulic actuators. Servo valve J761-003 is widely used in electro-hydraulic position, velocity, acceleration, force servo systems, and servo vibration generators.

 

The working principle of the electrohydraulic servo valve J761-003: If there is an electrical signal input, the armature drives the baffle to rotate, and the baffle is close to the nozzle, reducing the oil discharge area and flow rate of the nozzle, and increasing the oil pressure in front of the nozzle; Otherwise, the oil pressure in front of the nozzle decreases, causing the original electrical signal to be converted into a torque signal, resulting in a mechanical displacement signal that is then converted into an oil pressure signal.
