Johnson Controls MP823C001 Actuator

The Johnson Controls MP823C001 Actuator is a 25-square-inch pneumatic valve actuator engineered for precise positioning of globe valves in hot water, chilled water, and steam applications. Built for compatibility with VG7000 and VG2000 series valves, this spring return stem up unit features a 3-7 PSI spring range and a repeatable 3/4 inch stroke. The rugged, corrosion-resistant housing protects a high-performance EPDM diaphragm, ensuring a constant effective area throughout the full stroke for reliable linear output. Designed for demanding HVACR environments, it handles a max control pressure of 25 PSI and operates across an ambient temperature range of -20°F to 150°F. The 1/4 inch OD barbed fitting allows for quick integration with standard pneumatic poly tubing. Note that this specific model is the actuator and yoke assembly only and does not include a mounting kit or positioner.

• Enhanced Durability: The die-formed carbon steel housing and stainless steel stem resist wear in high-humidity mechanical rooms.
• Reliable Fail-Safe: The spring return mechanism ensures the valve stem moves to the UP position upon loss of signal pressure.
• Field Versatility: Suitable for universal application across various media, including low-pressure steam and hydronic systems.
• Maintenance Friendly: Features a visual position indicator and a quick-fit coupler system to streamline troubleshooting and installation.

Common Questions

What valves are compatible with the MP823C001?
This actuator is specifically designed for use with Johnson Controls VG7000 and VG2000 globe valves, typically in the 1-1/2 inch to 2 inch size range. Professional verification of the yoke and linkage is required for other series.

Can the action be reversed in the field?
Yes, the MP8000 series design allows for in-situ reversing of the pneumatic action, providing flexibility for normally open or normally closed configurations depending on the valve body used.

Does this unit include the mounting hardware?
No, the MP823C001 is provided without a mounting kit. Contractors must ensure they have the appropriate linkage or order a separate mounting kit to secure the actuator to the valve body.
