Alarm, Dry Pipe & Check Valves

Sprinkler Alarm Valves are the heart of a sprinkler system. They are engineered to prevent a reverse flow of water or air pressure from the installation into the fire-pump room. In case a fire sprinkler is activated (opened) due to fire, the sprinkler alarm valve will open and permit water flow into the system and a pressure switch gives a signal to activate the fire-pump.
