SQM53.467R1A Siemens Damper Motor

Overview

The Siemens SQM53.467R1A is a high-precision reversing actuator motor designed to provide reliable rotary motion for industrial and commercial combustion systems. Engineered for accuracy and repeatability, this actuator is commonly used to position flow control valves, butterfly valves, and dampers. It features a rugged industrial design that allows for mounting in any position, providing significant installation flexibility for complex burner configurations.
