Actuator SQM40 /SQM41
Actuators for air and gas
dampers
Electromotoric actuator up to 18 Nm torque
Clockwise and counterclockwise variants
Running times from 5 to 65 seconds
Different shaft ends available
Electronic version with analog control input
Internal position indication
Drive shaft can be disengaged
Variants with UL and CSA approval, as well as GL marine approval
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 modulating 3-position controllers or continuous controllers (e.g.,
4...20 mA) and/or...
... directly by burner controls
