The Belimo servo motor is designed for KTM  round metal air shutters. The servo motor with actuating torque 2 Nm is designed for controlling air dampers with cross section up to 0.4 m² installed in various ventilation and air conditioning systems. The Belimo CM 230 is controlled with a three-point control system. The damper is opened or closed by a single circuit control. The turning angle is adjusted by mechanical end stops. The power cable is 1m long.


The actuator is installed directly on the damper axis and locked with a special spindle clamp to prevent its turning-through. The actuator overload protection stops the actuator once it reaches the end positions. In case of installation of a magnet on the actuator housing, the gear is disengaged and the damper changes to manual operation mode.
