Function and Working Principle
The ABB V18345-1010221001 Valve Positioner operates through a closed-loop control principle to achieve accurate valve movement.
In an industrial automation system, the controller sends a desired valve position command to the positioner. The device compares the requested position with the actual valve position feedback and automatically adjusts the pneumatic output pressure until the actuator reaches the required position.
The working process includes:
- Receiving the control command from the automation system.
- Processing the requested valve position.
- Monitoring the actual valve position.
- Comparing the target position with feedback information.
- Adjusting pneumatic output pressure.
- Moving the valve actuator.
- Maintaining accurate valve positioning.
This feedback control method improves process accuracy and reduces valve control errors during continuous operation.
