JOHNSON CONTROLS M9220-GGA-3 Electric Actuator, 177 In. lbs Torque, Floating, Spring Return, Proportional

Johnson Controls M9220-GGA-3 actuator is employed in HVAC systems for precise valve control. It is used to modulate the opening and closing of valves in heating, ventilation and air conditioning applications. This actuator ensures efficient temperature and flow control, maintaining optimal comfort and energy efficiency. It offers stable environmental conditions and minimises energy consumption.

Working Mechanism:

• This actuator receives a control signal indicating desired valve position.
• It then actuates the motor based on the input signal's requirements.
• The motor's rotational motion is then translated into valve opening or closing.
• The actuator then monitors motor load to detect potential stall or overload conditions.
• If an overload is detected, the motor is deactivated to prevent damage.
• The electric actuator then uses reversible mounting to return the valve to its default position if needed.
• The integral switches then provide adjustable and fixed switch points for external control or feedback.

Features:

• It features a reversible mounting design for easy installation and facilitating the spring return in either direction.
• This M9220-GGA-3 electric actuator has an electronic stall detection facility for increased service life by deactivating the motor during an overload condition.
• It comes with an aluminium enclosure for increased protection of the internal components and corrosion resistance.
• This electric actuator offers integral auxiliary switches to facilitate an adjustable and a fixed switch point.

Compatible Accessories:

• Johnson Controls M9000-519 Valve Linkage Kit: This ball valve linkage kit is used in HVAC systems with the brand's actuator to control the opening and closing of ball valves, regulating fluid flow for temperature and pressure control.
