What is the function of a deluge valve in a fire protection system?

The function of a deluge valve in a fire protection system is to allow water to flow from the system to all connected sprinklers simultaneously. Deluge valves are specifically designed for deluge sprinkler systems, which are used in high-hazard areas where rapid fire spread is a concern. When the fire detection system activates, the deluge valve opens and releases water to all sprinklers at once instead of individually. This provides immediate and extensive coverage of water over the area, which is crucial for controlling or extinguishing fires quickly.

In contrast to other types of valves or components, the deluge valve's unique capability to simultaneously open multiple outlets enhances the effectiveness of the fire suppression system in critical situations. This approach is particularly useful in environments such as chemical processing plants or aircraft hangars, where traditional, individually activated sprinkler heads may not provide adequate protection.
