Application
The MP953D1131 is ideal for use in commercial HVAC systems where precise modulation of heating and cooling coil valves is required. Its reverse-acting design means the actuator opens the valve as signal pressure decreases, providing a predictable and safe response during pressure loss events. The spring return feature ensures the valve returns to its default position automatically, protecting equipment and maintaining system safety. Compatible with standard pneumatic control tubing, this actuator is straightforward to install and commission in new or retrofit HVAC systems.
