Johnson Controls MP823E001E Valve Actuator

The Johnson Controls MP823E001E Valve Actuator is a heavy-duty pneumatic valve actuator engineered for precise proportional control in commercial HVAC systems. Featuring a 25 square inch effective diaphragm area, this unit delivers consistent force to modulate valves in response to pressure changes from a pneumatic controller. It operates on a 9-13 PSI spring range with a 3/4" stroke, making it a reliable choice for steam, water, or glycol applications requiring a spring return stem up fail-safe position. Built for durability, the MP823E001E accommodates a 25 PSI max control pressure and includes a 1/4" OD barbed fitting for quick air line integration. This model comes equipped with a mounting kit, ensuring a secure mechanical interface for field replacement or new installations. Contractors trust this Johnson Controls actuator for its field-proven performance in maintaining terminal unit stability and system efficiency without the complexities of electronic components.

• Robust Construction: The 25 sq. in. diaphragm provides the high torque necessary for positive shut-off and stable modulation.
• Standardized Stroke: A 3/4" linear stroke ensures compatibility with a wide range of Johnson Controls globe valves.
• Fail-Safe Operation: Mechanical spring return to the stem-up position ensures system safety during a loss of pilot air.
• Ease of Installation: Included mounting hardware and barbed air connections reduce labor time during retrofit or maintenance cycles.

Common Questions

What is the maximum operating pressure for the MP823E001E?
The unit is rated for a maximum control pressure of 25 PSI. Exceeding this can damage the diaphragm or affect the calibration of the spring range.

Does this actuator include the mounting bracket?
Yes, this specific model includes the necessary mounting kit for direct installation onto compatible valve bodies.

Can I use this for both heating and cooling applications?
As long as the valve body and fluid media are compatible with the actuator's stroke and force output, this pneumatic unit is suitable for various hydronic and steam loops.
