The Barber Colman MP-423 is a 120V electric valve actuator designed for fast and accurate positioning of control valves. Featuring a 13-second full-stroke 90° motor, the MP-423 delivers up to 60 in-lb of torque and includes an internal switch (EA53) for additional control or feedback. This actuator is ideal for applications requiring quick response and reliable modulation in HVAC and industrial control systems. Now supported by Schneider Electric, it remains a trusted OEM solution.
