Deluge Valve is a quick release, hydraulically operated diaphragm actuated type of valve. It has three chambers, isolated from each other by the diaphragm operated clapper and seat seal. While in SET position, water pressure is transmitted through an external bypass check valve and restriction orifice from the system supply side to the top chamber, so that supply pressure in the top chamber act across the diaphragm operated clapper which holds the seat against the inlet supply pressure because of the 2 : 1 differential pressure design. On detection of fire the top chamber is vented to atmosphere through the outlet port via opened actuation devices. The top chamber pressure cannot be replenished through the restricted inlet port, thus it reaches less than half the supply pressure instantaneously and the upward force of the supply pressure lift the clapper allowing water to enter the system piping network and alarm devices.
A Deluge Valve is known as a system control valve in a deluge system, which is used for fast application of water in a spray system. They are used to protect areas such as power transformer installation, storage tank, conveyor protection etc. with the addition of foaming agent they do protect aircraft hangar and inflammable liquid fire.
