Function and Working Principle
The ABB V18345-1017121001 Valve Positioner operates through a closed-loop feedback control system to achieve accurate valve positioning.
In a typical industrial control loop, the controller sends a target valve position signal to the positioner. The device compares the requested position with the actual valve position feedback and adjusts pneumatic output pressure until the actuator reaches the required position.
The working process includes:
- Receiving the control signal from PLC, DCS, or automation controller.
- Processing the required valve position command.
- Monitoring actual valve actuator position.
- Comparing target position with feedback information.
- Adjusting pneumatic output pressure.
- Driving the actuator movement.
- Maintaining stable valve positioning.
This feedback control method improves valve accuracy, reduces positioning errors, and ensures stable operation in industrial processes.
