Product Description
The ABB V18345-1020221001 TZIDC Valve Positioner is an intelligent electro-pneumatic control valve positioner designed for precise control of pneumatic actuators in industrial process systems. It interprets a standard 4–20 mA control signal and adjusts the actuator’s position by regulating compressed air output, enabling accurate valve positioning according to the control system’s command. The unit incorporates advanced control algorithms, local configuration via LCD and push-buttons, and options for analog or digital feedback modules to facilitate commissioning, diagnostics, and maintenance. Its rugged IP65/NEMA 4X aluminum housing and flexible mounting make it suitable for linear and rotary actuators following IEC/DIN and VDI/VDE standards.
