SQM56.564R1G4R Siemens Damper Motor

Overview

The Siemens SQM56.564R1G4R is a high-torque, reversing electromotive actuator designed to provide precise rotary motion for large dampers, flow control valves, and butterfly valves. Part of the robust SQM5 series, this 110V actuator is engineered for industrial and commercial burner applications that require a high degree of modulating accuracy and repeatability. It features a clockwise (CW) rotational direction and is capable of handling exceptionally high-demand loads in HVAC and process heating systems.

Features

• High-precision modulating accuracy with low hysteresis gearing
• Self-checking mechanism and field-reversible rotational direction
• Integrated auto/manual selector switch and forward/reverse toggle for easy adjustments
• Equipped with two limit switches and four internal auxiliary switches (total of 6)
• Externally visible shaft position indicator for real-time monitoring
• Disengagement clutches for the drive shaft and cam drum to facilitate manual positioning
• Durable construction with maintenance-free gearwheels and bearings
