PRODUCTS CENTER
A dry alarm valve is used in dry sprinkler fire suppression systems. These systems are typically used in buildings where the ambient temperature is below 4℃. In standby mode, compressed air in the system network seals the fire suppression water on the supply side via the dry alarm valve. When a sprinkler activates, causing a drop in network air pressure to a certain value, the dry alarm valve opens, and pressurized water enters the system network to begin fire suppression.
