Spring return actuators in the range from 2 up to 30 Nm torque. All with the same wiring- and mounting concept! On the medium size two housing shells, welded together with ultrasound, reinforced with steel plates and hollow pillars, provide them with non-permeability and stability. In the event of a voltage interruption, the dampers or valves coupled with the actuator are moved automatically into the predefined emergency setting position. This means that your systems are reliably protected against expensive damage caused by frost, water and steam.
The unique rotary, fast running and linear actuators with “Controlled Power Off” function open up new perspectives in system protection. Their trend setting, Belimo-patented SuperCap Management ensures secure supply and unloading of the SuperCaps. These supply the devices in case of emergency with sufficient power to overcome short voltage interruptions up to 10 seconds. In the case of longer voltage interruptions they will move the dampers or valves if necessary to an individually predefined emergency setting position. This means that unnecessary operational breakdowns can be avoided and convenience limitations can be reduced.
