Johnson Controls MP865E001G Valve Actuator

The Johnson Controls MP865E001G is a heavy-duty pneumatic valve actuator designed for precise proportional control in commercial HVACR systems. This 100-square-inch effective diaphragm area actuator provides powerful positioning force for larger valves, ensuring reliable operation under high close-off requirements. Featuring a 9-13 PSI spring range and a 1 1/8-inch stroke length, the MP865E001G utilizes a spring return stem up configuration, making it a critical component for fail-safe applications. Its 1/4-inch OD barbed fitting air connection simplifies integration with standard pneumatic control lines, while the 25 PSI maximum control pressure rating accommodates most building automation environments. Engineered for durability, this HVAC valve actuator includes a complete mounting kit for efficient installation on various Johnson Controls globe valves. For technicians managing valve modernization, this pneumatic actuator replacement offers the mechanical advantage necessary for maintaining tight shut-off and consistent flow modulation in steam or water systems.

• High Torque Output: The 100-square-inch diaphragm provides the necessary force for high pressure drop applications.
• Precision Modulation: The 9-13 PSI spring range allows for accurate proportional control and sequencing with other pneumatic devices.
• Simplified Installation: Comes equipped with a comprehensive mounting kit for direct replacement and reduced field labor.
• Rugged Construction: Designed to withstand high ambient temperatures and harsh mechanical room environments.

Common Questions

What is the fail-safe position of the MP865E001G?
This model is configured for spring return stem up, meaning the actuator will retract the stem to the up position upon loss of control air signal.

Can this actuator be used on valves from other manufacturers?
While primarily designed for Johnson Controls series valves, it can be adapted to other proportional pneumatic valves provided the stroke length and mounting bracket compatibility match the 1 1/8-inch specification.

Is the mounting hardware included for field retrofits?
Yes, the MP865E001G includes the standard mounting kit required for securing the actuator to the valve bonnet and stem assembly.
