Johnson Controls MP823C001A Actuator

The Johnson Controls MP823C001A is a heavy-duty pneumatic valve actuator designed for proportional control of valves in HVAC systems. Featuring a 25 square inch effective diaphragm area, this spring return pneumatic actuator provides reliable stem up action upon loss of air pressure. It operates within a 3-7 PSI spring range and delivers a consistent 3/4 inch stroke, making it a standard choice for modulating steam or water flow. Built with a rugged aluminum housing and a synthetic rubber diaphragm, the MP823C001A handles a 25 PSI maximum control pressure. The unit includes a 1/4 inch OD barbed fitting for secure air line connection and comes complete with a universal mounting kit for streamlined field installation. This Johnson Controls MP8000 series component is engineered for high-cycle durability in demanding commercial environments, ensuring precise valve positioning and long-term system stability for proportional pneumatic control applications.

Key Benefits

• High Force Output: The 25 sq. in. diaphragm provides ample torque for positive valve seating against high pressure drops.
• Field Versatility: Included mounting hardware allows for cooling or heating valve integration across various HVAC pneumatic systems.
• Fail-Safe Operation: Mechanical spring return ensures the valve returns to its stem up position during power or signal failure.
• Robust Construction: Precision-molded diaphragm maintains flexibility and response accuracy across a wide temperature range.
