SQM50.467R1H3 Siemens Damper Motor

Overview

The Siemens SQM50.467R1H3 is a high-precision reversing actuator designed for the accurate positioning of air and gas dampers, flow control valves, and butterfly valves in industrial burner applications. Part of the SQM5 series, this electromotive actuator is engineered for tasks requiring a high degree of modulating accuracy and repeatability. It features a robust die-cast aluminum housing and impact-resistant plastic covers, ensuring durability in demanding environments. The modular design allows for field-exchangeable circuit boards and potentiometers, providing significant flexibility for various control requirements.
