Working Principle
The ABB V18345-1021420001 Valve Positioner works through a feedback-based automatic positioning process.
The controller sends a required valve position command to the positioner. After receiving the signal, the device compares the requested position with the actual valve position and adjusts the pneumatic output accordingly.
The operating process includes:
- Receiving the control signal from PLC, DCS, or automation equipment.
- Processing the target valve position command.
- Measuring actual actuator position.
- Comparing target position and feedback position.
- Adjusting pneumatic output pressure.
- Driving the actuator to the required position.
- Maintaining stable valve operation.
This closed-loop regulation improves valve positioning accuracy and ensures consistent process control performance.
