Johnson Controls MP823E001A Valve Actuator

The Johnson Controls MP823E001A is a robust pneumatic valve actuator designed for precise proportional control in HVAC applications. This 25-square-inch effective diaphragm area actuator features a 9-13 PSI spring range and a 3/4" stroke, providing the necessary force for reliable fluid regulation. Built with a spring return stem up configuration, it ensures a fail-safe position during control air loss. The unit includes a 1/4" OD barbed fitting for air connections and supports a maximum control pressure of 25 PSI. Engineered for compatibility with vintage and modern Johnson Controls valve bodies, this replacement pneumatic actuator is essential for maintaining system pressure balance and flow accuracy. The included mounting kit facilitates straightforward field installation, making it a preferred choice for contractors managing pneumatic control systems in commercial mechanical rooms.

• Optimized Force Output: The 25 sq. in. diaphragm provides consistent torque and thrust for 3/4" stroke valve bodies.
• Fail-Safe Reliability: Internal spring return mechanism automatically moves the stem to the "up" position upon signal failure.
• Versatile Application: Standard 9-13 PSI operating range integrates seamlessly with pneumatic thermostats and controllers.
• Durable Construction: Built to withstand the rigorous demands of industrial mechanical environments.

Is this actuator compatible with other valve brands?
The MP823E001A is specifically designed for Johnson Controls valves; however, with the appropriate mounting bracketry, it can sometimes be adapted to compatible globe valves. Always verify stem threading and stroke length before installation.

What is the maximum operating pressure for this unit?
This pneumatic actuator is rated for a maximum control pressure of 25 PSI. Exceeding this limit may damage the diaphragm or affect the spring calibration.

How do I connect the air line?
The unit features a standard 1/4" OD barbed fitting, designed for secure attachment of pneumatic tubing typically used in control loops.
