Johnson Controls M9220-AGA-3 Actuator

The Johnson Controls M9220-AGA-3 is a heavy-duty spring return direct coupled actuator designed for floating control applications in demanding HVACR systems. Delivering a robust 177 lb-in torque, this 24Vac/Vdc actuator is engineered for precise positioning of large dampers and valves, ensuring reliable fail-safe operation during power loss. With a 150-second power-on run time, it provides smooth, consistent modulation without hunting. This model features a 48-inch cable with wire leads for straightforward field wiring and integration into existing control loops. The M9220-AGA-3 is frequently utilized in high-static pressure environments where damper actuator replacement requires high-torque performance and industrial-grade durability. Its direct coupled mounting design eliminates the need for complex linkages, reducing mechanical failure points and installation labor for technicians managing large-scale air handling units.

• High Torque Output: Provides 177 lb-in (20 Nm) of torque for managing large surface area dampers.
• Fail-Safe Reliability: Mechanical spring return ensures the unit returns to a safe position during power interruptions.
• Versatile Power Compatibility: Operates on both 24Vac and 24Vdc for flexibility across different control panels.
• Simplified Wiring: Pre-installed 48-inch cable reduces the need for additional junction boxes and speeds up installation.
• Floating Control Logic: Ideal for 3-point floating control applications requiring incremental positioning.

Is the M9220-AGA-3 compatible with 3-point floating controllers?
Yes, this actuator is specifically designed for 24V floating control, making it compatible with most standard HVAC controllers that utilize 3-point incremental signaling.

Can this actuator be mounted on a round shaft?
The Johnson Controls M9220 series typically accommodates 1/2-inch to 3/4-inch round shafts or 3/8-inch to 5/8-inch square shafts using the standard coupler.

What is the typical application for 177 lb-in torque actuators?
These units are generally used for large control dampers, outdoor air intakes, or multi-section louvers where high air velocity requires significant holding force.
