What is a "deluge valve"?

A deluge valve is specifically designed for fire protection systems, functioning to open and allow a large volume of water to flow through in the event of a fire. When a fire is detected, the valve releases water into the system, typically feeding a network of open sprinkler heads or nozzles. This rapid release of water is intended to quickly suppress the flames over a wide area, making it highly effective in scenarios where a significant risk exists, such as in industrial applications or high-hazard areas.

Understanding the role of a deluge valve is crucial, as it is part of a broader fire suppression system that operates automatically when activated by heat or flames. This distinguishes it from other types of valves that may regulate water pressure or flow but do not serve the specific purpose of fire suppression.
