The Schneider Electric (Barber Colman) MP-461 Spring Return Proportional Actuator is a control part that varies the position of a damper or valve by converting electrical signals into mechanical action in HVAC systems in airflow and fluid control systems. It has a 50 in-lb torque rating with a 2-12 VDC or 120 V input and can be operated in a spring return mode to allow proportional adjustment with control input. It is placed in the control linkages, which facilitates accurate modulation, system responsiveness, accurate positioning, and achieving stable operational performance in commercial settings.
