BELIMO LF230/LF24
The LF series actuators with actuating torque 4 Nm are designed for controlling air dampers with cross section up to 0.8 m2 installed in various ventilation.
Application
The LF series actuators with actuating torque 4 Nm are designed for controlling air dampers with cross section up to 0.8 m2 installed in various ventilation and air conditioning systems and performing protection functions, as freezing protection, smoke detection, etc.
Design
The actuator moves the damper to its operating position while tensioning the return spring at the same time. In case of power supply cut-off, the damper moves back to its safe position by the spring energy. 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. The turning angle may be adjusted by a mechanical end stop.
