QRV Electrical Release Device
The electrical release device QRV is used for the electrical actuation of a type QRV quick release valve. The release device is only suitable for usage inside buildings. By applying voltage to the release device, the force stored in a spring assembly is suddenly released. In this case, a plunger activates the pilot valve integrated into the quick release valve and vents the upper pressure chamber. This drop in pressure causes the extinguishing agent pressure to push the closing piston into an open position. This in turn causes the quick release valve to open.
The manual release device QRV can also be fitted to the electrical release device QRV as an additional means of release (sold separately). Only one extinguishing agent cylinder valve each can be opened electrically by the application of the release device’s nominal voltage. The electrical actuator device is resettable using the reset tool (tool sold separately).
