HD Deluge Valve

 It is a hydraulically operated control valve designed to rapidly release water through a network of open nozzles. The valve is typically held closed by water pressure trapped in a priming chamber, keeping the system piping dry until activation. Once a fire detection system (like heat or smoke detectors) activates, pressure is released from the priming chamber, causing the valve to open automatically. Deluge valves are used in high-risk areas such as power transformer installations, storage tanks, and conveyor protection, where fast, total-area suppression is necessary.
