Working Principle
The ABB V18345-2010421001 Valve Positioner operates through an automatic feedback control process.
When the automation system sends a valve position command, the positioner receives and processes the signal. The device compares the requested position with the actual valve position and automatically adjusts pneumatic output pressure to achieve accurate positioning.
The operating process includes:
- Receiving the control signal from PLC, DCS, or automation equipment.
- Processing the required valve position command.
- Monitoring actual actuator movement.
- Comparing target and actual valve positions.
- Adjusting pneumatic output pressure.
- Controlling actuator movement.
- Maintaining stable valve operation.
This closed-loop control method improves positioning accuracy and ensures consistent process performance.
