Depending on the actuator type, the device is electrically connected via a lead or a terminal pre-assembled in the casing. The actuators are applied particularly in heating and air conditioningsystems, and can be used with 3-point controllers or switching contacts. Moreover, the product is available for DN15 to DN100 mixing valves.

SM 3 actuators are delivered with non-blocking toothed wheels made of metal (204 h), and are available in two versions, witha torque of 15 Nm or 30 Nm. Both versions are available witha quill drive shaft or a drive shaft with an adjustable yoke. Various adapters allow you to easily mount different components on the versatile console. The product is equipped with adjustable cams (by 15°; range:15°-345°), thanks to which you can set the angle freely. The angle is factory set to 90°. You can also adjust the angle manually by declutching the gear with a switch located on the casing. When manual adjustment is no longer necessary, the device will restart in normal mode. Optionally it can be delivered with a pre-assembled potential free limit switch. Dimensions are the same for all variants.
