Johnson Controls MP823E001 Actuator

The Johnson Controls MP823E001 Actuator is a field-proven pneumatic valve actuator specifically engineered for the precise positioning of chilled water, hot water, and steam control valves. Built with a 25-square-inch effective diaphragm area, this MP8000 Series model features a 9-13 PSI spring range and a reliable 3/4" stroke length. The assembly is designed for spring return stem up action, ensuring a fail-safe normally open position in the event of control signal loss. Its sturdy, die-formed carbon steel housing and EPDM synthetic rubber diaphragm provide consistent force and a constant effective area throughout the entire stroke, resisting technical degradation in demanding mechanical rooms. With a 1/4" OD barbed fitting air connection and a maximum control pressure of 25 PSI, this actuator integrates seamlessly into existing pneumatic control loops. Note that this unit is supplied as the actuator and yoke assembly without mounting kit, requiring proper linkage for final valve body installation.

• Universal Application: High-performance design optimized for hot water, chilled water, and steam control systems using VG7000 and VG2000 globe valves.
• Rugged Construction: Features a corrosion-resistant carbon steel housing and a chrome-silicon steel spring for long-term mechanical reliability in high-cycle environments.
• Visual Monitoring: Integrated position indicator allows for immediate field verification of the valve stem position and operation.
• Field Flexibility: The action is reversible in-situ, permitting modification to suit specific sequencing or control logic requirements.
• Thermal Stability: Rated for ambient operating temperatures ranging from -20°F to 150°F (-29°C to 66°C), maintaining pneumatic actuator performance across varying conditions.

Common Questions

Is the MP823E001 compatible with third-party globe valves?
While this actuator is technically optimized for Johnson Controls VG7000 and VG2000 series valves, it can be adapted to other globe valves provided the 3/4" stroke and mounting requirements align with the specific valve bonnet and stem dimensions.

Does this unit come with the necessary linkage for installation?
No, this part number is the actuator and yoke assembly only. A separate valve mounting kit is required to connect the actuator to the valve body.

Can I add a positioner to this actuator later?
Yes, the MP8000 series design allows for the field installation of a pneumatic valve positioner (such as the PY-1010) if your application requires sequential operation or increased positioning power.
