Product Overview
The ABB V18345-101052100N is a high-performance electro-pneumatic valve positioner from the ABB TZIDC series (V18345 platform), engineered to deliver precise, reliable control of pneumatically actuated control valves in demanding industrial process environments. This positioner converts a 4–20 mA electrical control signal into a proportional pneumatic output pressure, driving single- or double-acting actuators to the exact valve stem position commanded by the process controller. Featuring advanced microprocessor-based control logic, automatic zero and span calibration, and a robust die-cast aluminum housing, the V18345-101052100N ensures fast response, minimal air consumption, and long-term stability in continuous-operation loops. It is a direct-fit automation component for flow, pressure, temperature, and level control valves across the process industries.
