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.
