ZSFG-LEVER TYPE DELUGE ALARM VALVE

ZSFG model deluge valve is a one-way valve which via electric,engine or other ways to open,and make waterflow into sprinkler systems and meanwhile start to alarm,Deluge systems adopt open type fire sprinklers, it's will control by fire detection system,when get fire,fire detection system start to act and deluge alarm valve open,water where exist in pipeline flow into protect area pipeline flow into protect area pipeline,then make all the open type fire sprinklers start to spray together and issue sound,light alarm signal,ZSFG deluge alarm  valve widely used in these places like dangerous ground and high headroom ground,Also it can used for foam systems.This type should upright installlation,in the frezzing area,deluge alarm valve environment temperature should be more than 4 °C,wet type control deluge alarm valve should be keep in 4°C-70°C.
