We offer an assembly service for the actuator with the fitting for this product. More informationEmergency Belimo SF actuator for HVAC dampers or ball valves (e.g. Giacomini R250D with adapter). The actuator is designed for damper sizes up to approx. 4m2. The actuator is controlled by a DC 0-10V voltage signal.
In the event of a power interruption, the return spring begins to rotate the actuator to the default position. For example, in the event of a power failure, it closes the damper or ball valve. The same can be achieved in reverse, depending only on the initial position of the damper. The actuator is opened by a 0-10V signal.
