A deluge valve is a critical component of the deluge system used in fire protection services. During fire events, deluge valves are activated quickly and deliver a large volume of water over the protected area to extinguish the fire for protecting life and property. Because of this, deluge valves are known as the heart of a deluge system.
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.
What are Deluge Valves? Deluge systems deliver large quantities of water, over a large area, in a relatively short period of time. They are commonly used in fixed fire protection systems whose pipe system is empty until the deluge valve distributes pressurised water from open nozzles or sprinklers.
What is a deluge valve? HD deluge valve is a quick-opening, differential diaphragm-type valve for fire protection use. Deluge fire valve is used to control water overflow in Deluge, Pre-Action as well as Foam systems.
Consisting of unpressurized dry piping and open sprinkler heads, the deluge system is directly connected to a water supply and upon activation, a deluge valve releases the water to all the open sprinkler heads simultaneously.
A Deluge system (automatic High Velocity Water Spray System) is a fixed fire protection system, which totally floods an area with pressurized water through a system of piping with open nozzles & sprinklers.
Deluge valves are used to safeguard locations such as power transformers, storage tanks, conveyors, and other industrial applications. They also protect aircraft hangers from flammable liquid fires with the addition of a foaming agent. ( Types of Valves ) Operation of Deluge Valve.
Dec 14, 2020 · What is a Deluge Valve? Per NFPA 25 code 3.5.2, a Deluge Valve is defined as “a water supply control valve intended to be operated by actuation of an automatic detection system that is installed in the same area as the discharge devices.”
Deluge and preaction valves are for systems designed to protect an area with extra hazards or with contents highly sensitive to water exposure. Benefits. External Reset. Save time and effort with no need to remove the diaphragm cover. Higher Pressure Rating and Lower Pressure Drop.
Deluge valve. The deluge valve is the central control device that regulates the flow of water into the system. It remains closed under normal conditions but opens when a fire detection system or manual control signals the need for water discharge.
