SQM50.360R1 Siemens Damper Motor

Overview

The Siemens SQM50.360R1 is a high-precision reversing actuator designed for the accurate positioning of air dampers, gas dampers, and flow control valves. Part of the robust SQM5 series, this electromotive actuator is engineered for industrial and commercial burner applications that require a high degree of modulating accuracy and repeatability. The SQM50.360R1 is a base model configured for 110V operation, providing reliable rotary motion to maintain optimal fuel-to-air ratios in combustion systems.
