Working Principle
The ABB V18345-2010521501 Valve Positioner works by comparing the desired valve position command with the actual valve position feedback and automatically adjusting pneumatic pressure to achieve accurate positioning.
The operating process includes:
- The automation system sends a control signal to the valve positioner.
- The positioner analyzes the requested valve position.
- The internal control system compares the target position with actual valve movement.
- Pneumatic output pressure is adjusted accordingly.
- The actuator moves the valve until the correct position is reached.
- Continuous feedback maintains stable valve operation.
This closed-loop control method allows the valve positioner to maintain accurate positioning even when process conditions change.
