Working Principle
The ABB V18345-2010521001 Valve Positioner operates through an automatic feedback control process.
During operation, the automation system sends a target valve position command to the positioner. The device processes the input signal and compares the required position with the actual valve position feedback.
The operating process includes:
- Receiving the control signal from the automation system.
- Processing the required valve position.
- Detecting the actual actuator position.
- Comparing target and actual positions.
- Adjusting pneumatic output pressure.
- Controlling actuator movement.
- Maintaining accurate valve positioning.
Through continuous feedback adjustment, the positioner can compensate for mechanical friction, actuator load changes, and process variations, ensuring stable and precise valve operation.
