Description
The Johnson Controls MP823D001 is a heavy-duty pneumatic valve actuator engineered for reliable, precise control of valves in commercial HVAC and building automation systems. With a 25 square inch diaphragm area, this actuator delivers the force necessary to operate a wide range of two-way and three-way control valves in demanding pneumatic control applications.
Key Specifications
- Spring Range: 4–8 PSI
- Stroke: 3/4 inch
- Diaphragm Area: 25 square inches
- Maximum Control Pressure: 25 PSI
- Air Connection: 1/4″ OD barbed fitting
- Actuator Action: Spring return, stem up
- Mounting Kit: Not included (sold separately)
Product Overview
The MP823D001 operates on a 4–8 PSI spring range, making it compatible with standard pneumatic control systems. The spring return stem-up action ensures a defined fail-safe position upon loss of control air pressure — a critical safety feature for HVAC valve control. The 1/4″ OD barbed fitting air connection allows for straightforward tubing connections to pneumatic control lines.
