SQM53.464R1G7R Siemens Damper Motor

Overview

The Siemens SQM53.464R1G7R is a high-precision reversing actuator designed for the accurate positioning of air and gas dampers, flow control valves, and butterfly valves. Engineered for industrial and commercial burner applications, this electromotive actuator provides reliable rotary motion with a specific focus on modulating accuracy and repeatability. The R1G7R variant is characterized by its clockwise (CW) rotation, integrated 4-20 mA control module, and a dual-ended square shaft, making it a robust solution for complex HVAC and combustion systems.
