Actuator SQM40.../SQM41...
Actuators for air and gas
dampers
Electromotoric actuator up to 18 Nm torque
Clockwise and counterclockwise variants
Running times from 5 up to 65 seconds
Different shaft ends available
Electronic version with analog control input
Internal position indication

The SQM40.../SQM41... and this Data Sheet are intended for use by OEMs which
integrate the actuators in their products!
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
