Siemens control motors are highly versatile modulating actuators used for the positioning of flow control valves, butterfly valves, dampers, or any application requiring rotary motion.
SQM40/41: Series for up to 90 in-lbs application
The SQM40.../SQM41... actuators are suited for driving oil pressure controller, butterfly valves, dampers or for use on other applications that require rotary motion.
Areas of application are oil and gas burners of medium to higher capacity as well as thermal process plants.
The actuators are used primarily for load-dependent control of the flow of gas, oil and combustion air:
In connection with modulating 3-position controllers or continuous controllers (e.g., 4…20 mA) and/or…
... directly by burner controls
