Tyco Fire & Building Products introduces its newest deluge valve, the Model DV-5, which features a single moving piece that allows for a trouble-free way to externally reset the valve. Traditional deluge valves have numerous internal parts. The rubber diaphragm also eliminates rust accumulation. Can be used in deluge, preaction and special–type (i.e., foam-water) fire protection systems. Designed for vertical and horizontal applications.
