How the G772K620A Servo Valve Works
- An electrical command signal energizes the torque motor.
- The motor moves a flapper between two nozzles.
- Pressure differential shifts the main spool.
- The spool regulates hydraulic flow to the actuator.
- Mechanical feedback ensures precise position control.
This closed-loop process provides fast and highly accurate motion control.
