Product Overview
The ABB V18345-1027420001 Valve Positioner is an industrial electro-pneumatic control device designed for precise positioning and reliable operation of pneumatic control valves in process automation and industrial control systems.
As a key component in automatic valve regulation systems, the valve positioner provides communication between the control system and pneumatic actuator. It receives electrical control signals from PLC, DCS, or industrial controllers and converts these signals into accurate pneumatic output adjustments to control valve actuator movement.
The ABB V18345-1027420001 uses closed-loop feedback control technology to continuously monitor the actual valve position. By comparing the required position command with the real actuator position, the positioner automatically adjusts pneumatic output to correct deviations and maintain accurate valve operation.
With dimensions of 168.5 × 101 × 114.5 mm and a weight of 1.7 kg, the compact design allows convenient installation and integration into various industrial valve actuator applications.
Typical applications include:
- Process automation systems
- Pneumatic control valve systems
- Chemical and petrochemical plants
- Power generation equipment
- Oil and gas processing systems
- Water treatment facilities
- Industrial instrumentation systems
- Manufacturing automation applications
