SQM53.482R2G3 Siemens Damper Motor

Overview

The Siemens SQM53.482R2G3 is a high-precision reversing actuator motor designed for the positioning of air and gas dampers, flow control valves, and butterfly valves in industrial burner applications. This electromotive actuator is engineered for heavy-duty performance, providing reliable torque to manage combustion air, gas flow, and oil volume in medium to large capacity burner systems. It is characterized by its robust die-cast aluminum housing and its ability to handle demanding environments while maintaining a high degree of modulating accuracy and repeatability.
