Function and Working Principle
The ABB V18345-1010120001 Valve Positioner operates through a closed-loop control system to achieve accurate valve positioning.
During operation, the automation controller sends a target valve position command to the positioner. The positioner analyzes the input signal and compares it with the actual valve position feedback. According to the difference between the desired and actual positions, the device adjusts pneumatic pressure to control the actuator movement.
The working process includes:
- Receiving the control signal from the automation system.
- Processing the required valve position command.
- Monitoring the actual valve position.
- Comparing target and current positions.
- Adjusting pneumatic output pressure.
- Moving the actuator to the correct position.
- Maintaining stable valve operation.
This control method improves process accuracy and ensures consistent industrial performance.
