SQM50.467R2G3 Siemens Damper Motor

Overview

The Siemens SQM50.467R2G3 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 damper motor provides reliable rotary motion to optimize the combustion process. It is part of the robust SQM5 series, known for its modular design, high modulating accuracy, and repeatability, making it a critical component in medium to large capacity oil and gas burner systems.

Features

• High modulating accuracy with minimal backlash for precise control
• Internal auto/manual selector switch and manual forward/reverse toggle switch for simplified commissioning
• Disengagement clutches for the drive shaft and cam drum to allow quick manual alignment
• Externally visible position indicator for easy monitoring of the shaft angle
• Modular design supports field-exchangeable circuit boards, potentiometers, and shafts
• Durable die-cast aluminum housing with impact-proof and heat-resistant plastic covers
• Integrated limit and auxiliary switches for enhanced operational control
