The Barber Colman MP-445 is a 120V electric proportional valve actuator with a 50-second stroke time and non-spring return (NSR) functionality. Designed for precise modulation and control of HVAC valves, the MP-445 provides smooth, reliable positioning in building automation and process systems. With its proven performance and OEM-grade construction, this actuator is ideal for retrofits and new installations. Now supported by Schneider Electric, it maintains compatibility with legacy Barber Colman equipment.
