Honeywell MP953F1101 Actuator RA Close/Rise 5 PSI

The Honeywell MP953F1101 Actuator is a pneumatic part used to control the flow of steam or water in the HVAC system, When the pressure of air builds up inside the actuator, the pressure pushes the spring and the arm of the actuator moves forward and turns the valve off. On the other hand, increased air pressure enables the spring to bring the arm back to the position that closes the valve. This 5 PSI actuator works with compressed air to open and close valves with the help of signals that are received from thermostats or building automation systems.
