he ABB V18345‑1010421001 Valve Positioner is a smart electro‑pneumatic valve positioner from ABB’s TZID/TZIDC series, engineered for precise control of pneumatic actuators on industrial control valves. This intelligent device accepts 4–20 mA control signals and translates them into accurate pneumatic output to position the valve stem or rotary actuator precisely, enabling stable regulation of flow, pressure, and other process variables.
