Siemens SQM53.460R1A

The Siemens SQM53.460R1A is a heavy-duty, modulating damper actuator designed for precise control of air and fuel flow in combustion systems. This position-proportional actuator delivers 200 in-lbs of torque with a 25-second travel time for 90° rotation. Operating on 110V power, it is ideal for use in industrial burners, boilers, and combustion air control systems. The actuator is configured for counterclockwise rotation and ships without a shaft, allowing customization for specific mechanical setups.
