SQM53.460R1A Siemens Damper Motor

Overview

The Siemens SQM53.460R1A is a high-precision, reversing rotary actuator designed to position flow control valves, butterfly valves, and dampers in industrial and commercial burner applications. Engineered for accuracy and repeatability, this actuator is part of the SQM5 series, which is known for its durable construction and modular design. It is particularly well-suited for systems requiring precise modulating control of gas, oil, and combustion air to enhance performance and product quality.

Features

• Self-checking and high modulating accuracy with 250 repositions through 90 degrees of travel
• Internal auto/manual selector switch and manual forward/reverse toggle switch for easy adjustment and commissioning
• Externally visible shaft position indicator for quick status monitoring
• Field-reversible rotation (counterclockwise by default) to accommodate various mounting needs
• Disengagement clutches for the drive shaft and cam drum to facilitate manual settings
• Modular design supports field-exchangeable circuit boards and potentiometers

Specifications

• Model: SQM53.460R1A
• Operating Voltage: AC 110-120 V (50/60 Hz)
• Torque: 200 in-lb (25 Nm)
• Running Time: 25 seconds for 90 degrees (at 60 Hz)
• Switches: 6 internal SPDT switches (2 limit, 4 auxiliary)
• Shaft Type: None (shaft must be ordered separately)
• Rotation: Counterclockwise (CCW)
• Control Type: Position proportional or floating control (via AGA56.1A97 board)
• Protection Rating: UL recognized, CSA certified, and CE approved

Applications

• Positioning of air and gas dampers in medium to large capacity oil and gas burners
• Load-dependent control of gas flow, oil volume, and combustion air volume
• Integration with flow control valves and butterfly valves in industrial process heating
• Use in dual-fuel applications where separate high/low fire positions are required
• Systems requiring an “economy position” to fully close dampers when the burner is offline
