SQM50.467R1Z3 Siemens Damper Motor

Overview

The Siemens SQM50.467R1Z3 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 electromotive actuator provides reliable rotary motion with a high degree of modulating accuracy and repeatability. Its robust die-cast aluminum housing and impact-proof plastic covers make it suitable for demanding environments.

Features

• High torque output of 140 in-lbs for reliable damper and valve control
• Integrated auto/manual selector switch and manual forward/reverse toggle for easy adjustments
• Externally visible position indicator for quick status monitoring
• Low hysteresis gearing with double-offset drive for precise rotational resolution
• Field-reversible rotational direction, set to counter-clockwise (CCW) by default
• Self-locking synchronous motor to maintain position upon power loss
• Supports multiple input signals including 4 to 20 mA, 0 to 135 Ohms, and 0 to 10 VDC via exchangeable circuit boards
