Description:

The wet alarm valve is a key component of the water sprinkler system. It can combine with closed sprinklers, water flow indicator, vent valve etc. When the temperature in protected area rises because of fire or other reasons until the glass bulb burst, the sprinkler will open and discharge. Then lateral pressure of wet alarm valve system will drop and be lower than water supply pressure, differential pressure can open valve flap (wet alarm valve will open) to discharge and extinguish.
