SQM50.464R1Z3R Siemens Damper Motor

Overview

The Siemens SQM50.464R1Z3R is a high-precision reversing actuator designed for the accurate positioning of dampers, butterfly valves, and flow control valves. Engineered for industrial and commercial burner applications, this motor provides reliable rotary motion for load-dependent control of gas, oil, and combustion air. It features a robust die-cast aluminum housing and is specifically configured for clockwise rotation with a durable 3/8 inch square shaft.

Features

• Reversing actuator providing precise rotary motion for advanced modulation
• Equipped with two limit switches and four internal, easily adjustable auxiliary switches
• Includes a fully closed economy position switch for burner-off cycles
• Features drive shaft and cam drum disengagement clutches for quick manual alignment
• Built-in auto/manual selector and manual forward/reverse toggle switches for local control
• Field exchangeable circuit boards and potentiometers for versatile system integration
• Durable construction with impact-proof, heat-resistant plastic covers and die-cast aluminum housing
