Johnson Controls MP823C001E Actuator

The Johnson Controls MP823C001E is a heavy-duty pneumatic valve actuator designed for precise proportional control in commercial HVACR systems. This unit features a 25 square inch effective diaphragm area, providing 38 lb-in of torque to ensure reliable modulation of globe valves under varying load conditions. Engineered with a 3-7 PSI spring range and a 3/4-inch stroke, the MP823C001E utilizes a spring return stem up action, ensuring a fail-safe position during a loss of terminal pressure. The assembly includes a robust MP8000 series mounting kit and a 1/4-inch OD barbed fitting for seamless integration into existing pneumatic control loops. Rated for a 25 PSI maximum control pressure, this actuator is built for long-term stability in high-demand environments. Contractors favor the MP823C001E for its field-reversible action and compatibility with VG7000 series valves, making it a standard choice for terminal unit control and air handling applications requiring precise pressure-to-stroke ratios.

• Field-Proven Reliability: Molded synthetic rubber diaphragm provides consistent performance across the full 0 to 150°F ambient temperature range.
• Precise Throttling: The 3-7 PSI spring span allows for accurate sequencing with other pneumatic components in complex Ahu control systems.
• Integrated Mounting: Includes all necessary hardware for direct installation on 1/2-inch through 2-inch Johnson Controls valves.
• Durable Construction: Die-cast aluminum housing protects internal components from mechanical stress and environmental debris.

Common Questions

What is the fail-safe position of the MP823C001E?
This model is configured for spring return stem up, meaning the actuator will return the valve stem to the upward position upon loss of air pressure.

Can this actuator be used with non-Johnson Controls valves?
While primarily designed for the VG7000 and V-3000 series, compatibility depends on the bonnet size and stroke length; a specific pneumatic actuator mounting kit may be required for secondary brands.

How do I verify the diaphragm integrity?
Technicians should perform a pressure decay test at the 1/4-inch barbed fitting to ensure the 25 square inch diaphragm maintains the 3-7 PSI calibration without leakage.
