Function and Working Principle
The ABB V18345-1010121001 Valve Positioner operates through a feedback-based control process to achieve accurate valve positioning.
In an industrial automation system, the controller sends a desired valve position command to the positioner. The positioner compares the target position with the actual valve position and automatically adjusts the pneumatic output pressure to move the actuator until the correct position is achieved.
The working process includes:
- Receiving the control signal from the automation system.
- Processing the required valve position command.
- Monitoring the actual valve position.
- Comparing the difference between target and actual position.
- Adjusting pneumatic pressure output.
- Controlling actuator movement.
- Maintaining accurate valve positioning.
This closed-loop operation improves process stability and ensures reliable valve performance.
