Description
The Honeywell MP953D1172/U Valve Actuator provides proportional movement to control compatible control valves in HVAC systems, regulating the flow of steam, hot water, or chilled water through the piping circuit. This hydraulic actuator converts changes in air pressure into linear valve stem movement, allowing precise adjustment of valve position in response to system control requirements. It is mounted directly to the valve assembly and connects to the air flow control line for coordinated operation with the building control system. Reliable valve positioning supports stable fluid flow and consistent temperature regulation throughout the system.
