The 1-1/2 thru 8 inch (DN40 thru DN200), Model DV-5 Deluge Valves arediaphragm type valves designed for vertical or horizontal installation and forfire protection system service. They are used as “automatic water controlvalves” in deluge, preaction, and special types of fire protection systems suchas foam-water and double interlock systems. When properly trimmed, the DV-5Valves are also able to provide actuation of fire alarms upon system operation.
The diaphragm style design of the DV-5 Valve allows externalresetting - providing for easy resetting of a deluge or preaction systemwithout having to open a valve handhole cover to manually reposition a clapper and/orlatch mechanism. Simply repressurizing the diaphragm chamber resets the valve.
The one-piece, diaphragm style design of the DV-5 also allowsinternal and external coating of the valve to provide corrosion resistance. Theinternal corrosion resistance offered by the Rilsan coating makes the DV-5 suitablefor most seawater and brackish water supplies when utilized in deluge systems.The external corrosion resistance of the Rilsan coating permits the use of theDV-5 in corrosive atmospheres associated with many types of industrialprocessing plants and outdoor installations.
