Johnson Controls MP823D001A Valve Actuator

The Johnson Controls MP823D001A is a robust, 25-square-inch pneumatic valve actuator designed for precise proportional control in commercial HVAC systems. This spring return stem-up unit is engineered for medium-to-large valves, featuring a 3/4-inch stroke and a 4-8 PSI spring range for reliable fail-safe operation. Utilizing a 1/4-inch OD barbed fitting air connection, this proportional control actuator handles up to 25 PSI maximum control pressure, ensuring consistent performance in high-demand environments. The inclusion of a universal mounting kit simplifies field installation and retrofitting onto existing valve bodies. Its rolling diaphragm design minimizes friction and hysteresis, providing the linear force necessary for accurate seat positioning. This pneumatic actuator is a critical component for technicians requiring dependable modulation in hydronic heating or cooling loops, offering the durability expected from industrial-grade Johnson Controls pneumatic parts.

• Optimized Control: The 4-8 PSI spring range allows for precise sequencing in complex pneumatic control systems.
• Field Ready: Supplied with a complete mounting kit to reduce downtime during emergency replacements or system upgrades.
• Durable Construction: The 25-square-inch effective diaphragm area provides high close-off force for demanding valve applications.
• Fail-Safe Integrity: Spring return functionality ensures the valve returns to the stem-up position during a loss of pilot air.

Common Questions

What is the maximum air pressure for the MP823D001A?
The unit is rated for a maximum control pressure of 25 PSI. Exceeding this limit can damage the rolling diaphragm or compromise the stroke accuracy.

Can this actuator be used for both water and steam valves?
Yes, provided the valve body is compatible with the 3/4-inch stroke and the mounting hardware matches the bonnet diameter of the specific valve assembly.

Is the mounting bracket included with this part number?
Yes, this specific model includes the necessary mounting kit for securing the actuator to the valve yolk.
