Johnson Controls MP867D001G Actuator

The Johnson Controls MP867D001G is a heavy-duty pneumatic valve actuator designed for precise flow control in demanding HVACR applications. Featuring a 100 square inch effective diaphragm area, this unit provides the necessary force to operate larger valves against high close-off pressures. The actuator operates on a 4-8 PSI spring range with a 1 1/2" stroke, utilizing a spring return stem up configuration to ensure fail-safe positioning during a loss of control air. Built with a rugged die-cast aluminum housing, it includes a 1/4" OD barbed fitting for secure air line connections and supports a 25 PSI maximum control pressure. For contractors performing field replacements or new installations, this Johnson Controls actuator comes complete with the necessary mounting kit, ensuring seamless integration with compatible valve bodies. This industrial-grade component is engineered for linear positioning and long-term reliability in pneumatic control loops.

Key Technical Benefits

• High Torque Output: The 100 sq. in. diaphragm provides superior thrust for managing high-pressure steam or water applications.
• Fail-Safe Operation: Mechanical spring return ensures the valve stem moves to the up position upon pneumatic signal failure.
• Precise Control: The 4-8 PSI sequencing range allows for accurate proportional control within complex pneumatic systems.
• Durable Construction: Engineered to withstand harsh mechanical room environments without degradation of the diaphragm or housing.
• Standardized Fitment: Includes a universal mounting kit designed specifically for Johnson Controls valve bodies to reduce labor time.

Common Questions

What is the maximum air pressure for the MP867D001G?
This actuator is rated for a maximum control pressure of 25 PSI. Exceeding this limit may damage the internal diaphragm.

Does this unit include the mounting hardware?
Yes, the MP867D001G is supplied with the requisite mounting kit for field installation on compatible linear valves.

Can the spring range be adjusted in the field?
The 4-8 PSI range is factory-set; however, fine-tuning of the start point can be achieved via the adjusting nut on the valve stem linkage during calibration.
