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 pressurized water from open nozzles or sprinklers.

Deluge systems contain more components and equipment than wet pipe and dry systems. So, for that matter they are more complex. Detection systems can include heat, smoke, ultraviolet (UV), or infrared (IR).

Applications for Deluge Valves

Deluge systems are used in conditions that require quick application of large volumes of water. They create a ‘buffer zone’ in hazardous areas or in areas where fires can spread rapidly. They can also be used to cool surfaces to prevent deformation or structural collapse. Or to protect tanks, transformers, or process lines from explosions.

Other examples include tanks containing combustible solutions; equipment pits; storage or process areas containing substances with a low flash point; or product handling systems.
