Actuators for air and gas dampers

Description

Features

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.

 45 or 90 in-lb

 Clockwise and counterclockwise versions

 Running times of 12 or 25 seconds

 Various drive shaft options

 Drive shaft disengagement clutch

 C-UL-US, CE approved

 NEMA 4 weatherproof enclosure

 Internal position indication

 Mounting brackets available to replace competitive actuators

 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.
