Description
The TYCO Aluminum Bronze DV-5 Deluge Valves are available to provide an alternative material of construc-tion to that of the standard nylon coated ductile iron DV-5 Deluge Valve described in Technical Data Sheets TFP1305, TFP1335, and TFP1338. Available in 2 inch to 8 inch (DN50 to DN200) Flange x Flange end connec-tions, Aluminum Bronze DV-5 Deluge Valves are diaphragm type valves designed for vertical or horizontal installation. They are used as auto-matic water control valves in deluge fire protection systems. The al ternate materials of construction are offered for use in corrosive environ ments where the standard nylon coated ductile iron would not be suit able, i.e. situa-tions where the system is continuously charged with sea water.
The diaphragm style design of the DV-5 Valve allows external resetting, pro-viding for easy resetting of a deluge system without having to open a valve handhole cover to manually reposition a clapper and/or latch mechanism. Simply re-pressurizing the diaphragm chamber resets the valve.
