Description
Deluge Valve is known as a system control valve in a deluge system,
used for fast application of water in a spray system. Deluge valve
protects areas such as power transformer installation, storage tank,
conveyor protection and other industrial application etc. With the
addition of foaming agent deluge valve can be used to protect aircraft
hangar and inflammable liquid fire.
Valve Operation
Deluge valve is a quick release, hydraulically operated diaphragm
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 acts across the diaphragm operated clapper
which holds the seat against the inlet supply pressure because of
differential pressure design.
