Deluge Valve

DESCRIPTION The Viking 2” ( DN50) Model E-1 Deluge Valve is a quick-opening, differential diaphragm, fl ood valve with one moving part. The deluge valve is used to control water fl ow in deluge and preaction sprinkler systems. The valve is held closed by system water pressure trapped in the priming chamber, keeping the outlet chamber and system piping dry. In fi re conditions, when the releasing system operates, pressure is released from the priming chamber. The deluge valve clapper opens to allow water to fl ow into the system piping.
