Description
The Honeywell MP953C1489/U 13″ Pneumatic Actuator 4-11 PSI 1-1/2″ Diaphragm converts regulated pneumatic pressure into linear mechanical movement to position compatible control valves within HVAC systems. A flexible diaphragm responds to changes in air pressure, producing controlled stem travel that adjusts valve position in proportion to the control signal. The actuator is configured for direct-acting operation and provides smooth modulation of fluid flow through connected piping. It mounts to compatible valve assemblies, delivering accurate positioning and stable response for heating and cooling control sequences.
