SQM41.164R11SC Siemens Actuator

Overview

The Siemens SQM41.164R11SC is a precision electromotoric actuator designed for the accurate positioning of dampers and flow control valves in combustion systems. Engineered for high reliability, this clockwise-rotating actuator is typically used to regulate the flow of gas, oil, or combustion air in industrial and commercial burner applications. Its robust design features a synchronous motor and a NEMA 4 rated enclosure, making it suitable for demanding environments that require precise rotary motion.
