The ABB V18345‑1010121001 TZIDC Electro‑Pneumatic Valve Positioner is an intelligent, configurable valve control device engineered for high‑precision actuator positioning in industrial automation systems. It converts electrical control signals (4–20 mA two‑wire) into accurate pneumatic output for valve actuators, ensuring stable and consistent flow regulation. The TZIDC positioner features rugged aluminum housing with IP65/NEMA 4X protection, making it suitable for harsh industrial environments.

This model supports HART communication for remote diagnostics and configuration, and the single‑acting fail‑safe output ensures safe valve positioning during power loss. Its standard design allows mounting on both linear and rotary actuators, with optional analog feedback modules for enhanced control accuracy. Ideal for use in process industries such as chemical, petrochemical, water treatment, and manufacturing, the V18345‑1010121001 improves responsiveness, reduces commissioning time, and enhances overall process performance.
