Honeywell MP909E1513 Spring Return Damper Actuator 9-15 PSI

The Honeywell MP909E1513 spring return damper actuator is used in different HVAC systems. It functions at a pressure range of 9–15 PSI and uses pneumatic signals to regulate the position of dampers. This actuator uses a spring return system whereby the damper is restored to a certain position usually the closed position in the absence of an air signal. This feature gives a backup method of operation of the system in case of power failure or loss of control signal. The MP909E1513 is typically applied to regulate the flow of air in HVAC systems by moving the position of the dampers in ducts as well as other parts.
