Use
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 3-position or modulating controllers (e.g. 4...20 mA), and/or ...
... directly by burner controls
