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

Features:

• 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
• Drive shaft can be disengaged
• Variants with UL and CSA approval, as well as GL marine approval

Accessories:

• Siemens Couplings
• Siemens Brackets
• CA Series Crank Arm Assembly (Coming Soon)
• Siemens AGA94.1 Bracket kit – SQM40/41 Actuator to Dungs DMK Butterfly Valve
