The operating process includes:
- Receiving the control command from the automation controller.
- Processing the required valve position signal.
- Detecting actual actuator movement.
- Comparing target and feedback positions.
- Adjusting pneumatic pressure output.
- Moving the valve actuator.
- Maintaining accurate valve positioning.
This closed-loop control method improves response performance, reduces positioning deviation, and ensures stable process operation.
