SQM56.564R1G7 Siemens Damper Motor

Overview

The Siemens SQM56.564R1G7 is a high-torque reversing actuator designed for the precise positioning of air and gas dampers, flow control valves, and butterfly valves in industrial combustion systems. Part of the robust SQM5 series, this electromotive actuator is engineered for applications requiring high modulating accuracy and repeatability. It features a durable design capable of operating in any mounting position and is particularly suited for medium to large capacity oil and gas burners.

Features

• High-torque performance suitable for large dampers and valves
• Reversible rotation allowing for flexible control configurations
• Internal auto/manual selector switch and manual forward/reverse toggle for easy adjustments
• Equipped with two limit switches and up to four internal auxiliary switches
• Disengagement clutches for the drive shaft and cam drum to facilitate manual setting
• Low hysteresis gearing with a double-offset drive for enhanced precision
• Externally visible shaft position indicator for quick status monitoring
• Field-exchangeable circuit boards and potentiometers for modular maintenance
