Product Structure & Construction

The GRAT quarter-turn electric actuator features a robust aluminum alloy housing engineered for demanding industrial valve control. Its integrated structure combines a drive motor, reduction mechanism, transmission mechanism, and control unit, delivering reliable torque transmission and multiple feedback options for precise rotary valve operation.

  • Drive motor: Converts electrical energy into mechanical power.
  • Reduction mechanism: Reduces speed while boosting output torque.
  • Transmission mechanism: Transfers torque directly to the controlled valve.
  • Control part: Receives command signals via the controller for accurate regulation.
