SIEMENS SQM MOTOR SERVO GAS BURNER
Actuators for air and gas dampers
Description SQM40/41… actuators are used for the positioning of flow control valves, butterfly
valves, dampers or any application requiring rotary motion. The SQM40/41… actuators
accommodate control input signals of 4 to 20 mA, 0 to 135 Ω, 2 to10 Vdc, position
proportional and floating control. SQM4… actuators are available with up to six internal,
easily adjustable switches.
The actuators are used primarily for precise flow control of gas, oil or combustion air.
The NEMA 4 SQM40/41… actuator may be mounted in any position. A selection of
mounting brackets and shaft options provides installation flexibility and allows for the
simple replacement of most competitive actuators.

Application
SQM40/41… actuators are suited for both industrial and commercial applications. On burner applications requiring high turndown and reliable ignition, the auxiliary switches can be applied to create separate positions for burner ignition and low fire. The shaft disengagement clutch allows for quick manual alignment of the actuator shaft with a connected valve or linkage.
