SQM53.467R1Z3 Siemens Damper Motor

Overview

The Siemens SQM53.467R1Z3 is a high-torque reversing actuator designed for the precise positioning of air and gas dampers, flow control valves, and butterfly valves in medium to large capacity burner systems. Engineered for reliability and high modulating accuracy, this electromotive actuator provides robust performance in demanding industrial and commercial combustion applications. It features a locking-proof synchronous motor and supports a wide variety of control signals through field-exchangeable electronic modules.

Features

• High torque output of 200 in-lbs for heavy-duty industrial applications
• Precision gear train with low hysteresis for repeatable positioning
• Internal and external position indicators for easy monitoring
• Field-reversible direction of rotation (set to counterclockwise by default)
• Accommodates up to six internal, easily adjustable auxiliary switches
• Modular design allows for the addition of exchangeable circuit boards and potentiometers
• Durable die-cast aluminum housing with heat-resistant plastic covers
