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.

• Running times of 12 or 25 seconds
• Various drive shaft options
• Drive shaft disengagement clutch
• C-UL-US, CE approved
• NEMA 4 weatherproof enclosure

• Modulating version accepts 4 to 20 mA, 0 to 135 Ω or 2 to10 Vdc
• Zero and span adjustment

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.
