Function and Working Principle
The ABB V18345-1010550001 Valve Positioner operates using a closed-loop control method to achieve accurate valve positioning.
In an industrial automation system, the controller sends a target position command to the valve positioner. The device compares the required valve position with the actual position feedback and adjusts the pneumatic output pressure until the actuator reaches the desired position.
The operating process includes:
- Receiving the control command from the automation system.
- Processing the required valve position.
- Monitoring the actual actuator position.
- Comparing target and feedback signals.
- Adjusting pneumatic pressure output.
- Moving the valve actuator.
- Maintaining accurate valve position.
This feedback control principle improves valve response performance and ensures stable operation in industrial processes.
