Product Overview
The ABB V18345-102045100P Valve Positioner is an industrial electro-pneumatic control device designed for accurate and reliable positioning of pneumatic control valves and actuators in process automation systems.
As an important field control component, the valve positioner provides communication between industrial control systems and pneumatic actuators. It receives electrical control signals from PLC, DCS, or other automation controllers and converts these signals into precise pneumatic output adjustments to control valve movement.
The ABB V18345-102045100P improves valve positioning accuracy by using feedback control technology. It continuously monitors the actual valve position, compares it with the required control command, and automatically adjusts the pneumatic output to maintain stable valve operation.
This valve positioner is suitable for demanding industrial environments where precise control, reliable operation, and long-term stability are required.
With dimensions of 168.5 × 101 × 114.5 mm and a weight of 1.7 kg, the ABB V18345-102045100P features a compact design that allows convenient installation on industrial valve actuator systems.
Typical applications include:
- Process automation systems
- Pneumatic control valve systems

The operating process includes:
- Receiving the electrical control signal.
- Processing the required valve position.
- Detecting the actual actuator position.
- Comparing the target and actual positions.
- Adjusting pneumatic output pressure.
- Moving the valve actuator.
- Maintaining accurate valve positioning.
This feedback control mechanism helps reduce valve position errors and improves overall process control stability.
