Function and Working Principle
The ABB V18345-1010420001 Valve Positioner operates using a closed-loop control principle to achieve precise valve positioning.
In a typical automation system, the controller sends a desired valve position command to the positioner. The device compares the requested position with the actual valve position feedback and automatically adjusts the pneumatic output pressure until the actuator reaches the target position.
The working process includes:
- Receiving the control signal from PLC, DCS, or process controller.
- Processing the required valve position command.
- Detecting the actual valve position.
- Comparing target and actual positions.
- Adjusting pneumatic output pressure.
- Controlling actuator movement.
- Maintaining accurate valve positioning.
This feedback-based control method improves process stability and ensures reliable valve operation.
