Technical Specifications (Typical for G772 Series)

Note: Exact performance depends on configuration code.

How the G772K620A Servo Valve Works

1. An electrical command signal energizes the torque motor.
2. The motor moves a flapper between two nozzles.
3. Pressure differential shifts the main spool.
4. The spool regulates hydraulic flow to the actuator.
5. Mechanical feedback ensures precise position control.

This closed-loop process provides fast and highly accurate motion control.
