Working Principle
The ABB V18345-1020221001 Valve Positioner operates through an automatic feedback regulation process.
During normal operation:
- The control system sends a valve position command.
- The positioner receives and processes the electrical signal.
- The actual valve position is detected through feedback.
- The device compares the target position with the actual position.
- Pneumatic output pressure is adjusted automatically.
- The actuator moves until the required position is achieved.
- The position is continuously maintained.
This closed-loop control process improves valve response speed, reduces position deviation, and provides stable operation under changing industrial conditions.
