Product Overview
The AZBIL AVP300 is a high-performance electro-pneumatic valve positioner engineered for precise control of pneumatic control valves in demanding industrial process environments. As a core component within the Azbil AVP series, the AVP300 receives a standard electrical input signal (typically 4–20 mA DC) and converts it into a proportional pneumatic output pressure to accurately position a valve actuator. This closed-loop positioner ensures that the valve stem reaches and maintains the exact position commanded by the control system, compensating for friction, packing resistance, and dynamic process forces. The AVP300 is widely deployed in flow, pressure, temperature, and level control loops where precise valve positioning and rapid response are critical to process quality and safety.
