WITA® actuators are distinguished by a compact design, durability and versatility. The product is equipped with a reversible synchronous motor and a maintenance-free gear. 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 44 actuators are equipped with a quill drive shaft, as well as EASY-Clip function, and are available in two versions, with a torque of 6 Nm or 10 Nm. SM 44.6 (6 Nm) is equipped with plastic non-blocking toothed wheels (240 h) designed for DN15 to DN32 mixing valves. SM 44.10 (10 Nm) version is equipped with metal non-blocking toothed wheels designed for DN40 to DN50 mixing valves. You can achieve the best fit by using the actuator with Minimix-E valves, which are the only valves equipped with the full set of EASY-Clip components.
As a matter of fact any WITA® mixing valve, or mixing valve of another manufacturer, can be equipped with EASY-Clip components, so that you can fully profit from it.Actuator components include cams adjustable by 15°(range:15°-345°) and manual adjustment at the front (can be locked). The angle of rotation is factory set to 90°. Optionally, SM 44 model can be delivered with apreassembled potential free limit switch.C series actuators can be used with controllers with solid state outputs.
Dimensions are the same for all versions, therefore you canuse SM 4 adapters.
