Descrizione del prodotto:

The wet alarm valve is a one-way valve that only allows water to flow into the sprinkler system in one direction and alarms at a specified flow rate. The wet alarm valve usually equals the water pressure before and after the valve disc (the water passes through the water pressure balance hole in the guide pipe to keep the water pressure balance before and after the valve disc).
ZSFZ-E Wet alarm valve is the key component of automatic sprinkler system. It consist of wet alarm valves, retard, water alarm, and other components (such as pressure switches, flow meters, closed head etc.). The system usually in standby state, the pressure pipe filled with water. When the fire starts and environmental temperature rise, lead to the fire sprinkler sensitive element (glass ball) action, sealing components off, auto start the wet system, water directly sprayed into the fire area and send alarm signals to the control center. It's widely used in some fire danger places(4℃ to 70℃ environment temperature), such as warehouse, hotel, mall, office or high building and garage etc.warehouses, alberghi, shopping malls, hospitals, theaters, office buildings, high-rise building and garage.
