Function and Working Principle
The ABB V18345-1020121001 Valve Positioner operates using a closed-loop feedback control principle to achieve precise valve positioning.
During operation, the automation controller sends a desired valve position command to the positioner. The device compares the target position with the actual valve position feedback and adjusts the pneumatic output pressure accordingly until the actuator reaches the required position.
The operating process includes:
- Receiving the control signal from the automation system.
- Processing the target valve position command.
- Detecting actual actuator movement.
- Comparing target and feedback positions.
- Adjusting pneumatic output pressure.
- Controlling actuator operation.
- Maintaining accurate valve positioning.
This closed-loop control method improves valve accuracy, enhances process stability, and ensures reliable operation in industrial environments.
