M9220-GGA-3 Actuator Johnson Controls

The Johnson Controls M9220-GGA-3 is a 20Nm spring-return type air valve actuator with power-off spring-return safety protection. When power is lost, the air valve will automatically return to the safe position, effectively avoiding risks in the HVAC system operation. It supports 0-10V proportional control signals and 24V AC/DC universal power supply, and is compatible with most building automation systems. It is equipped with electronic stall detection and overload automatic protection for the motor, extending its service life. It adopts a reversible direct installation structure, requiring no additional connecting rods, and comes with a manual override mechanism, making on-site installation, disassembly, and debugging convenient and efficient. The IP54 protected aluminum housing is resistant to dust and moisture, suitable for complex conditions such as machine rooms and ceilings, with low operating noise, precise action positioning, widely used in commercial buildings, factories, and HVAC air valve control, with strong stability and low maintenance costs.
