مشخصات:
The TYCO 1-1/2 inch to 8 inch (DN40 to DN200), DV-5 Deluge Valves are diaphragm type valves designed for vertical or horizontal installation and for fire protection system service. They are used as automatic water control valves in deluge, preaction, and special types of fire protection systems such as foam-water and double interlock systems. When properly trimmed, the DV-5 Valves are also able to provide actuation of fire alarms upon system operation. These valves are to be used only for hydraulically calculated systems. The diaphragm style design of the DV-5 Valve allows external resetting, providing for easy resetting of a deluge or preaction system without having to open a valve handhole cover to manually reposition a clapper and/or latch mechanism. Simply repressurizing the diaphragm chamber resets the valve. The one-piece, diaphragm style design of the DV-5 also allows internal and external coating of the valve to provide corrosion resistance. The internal corrosion resistance offered by the RILSAN coating makes the DV-5 suitable for most seawater and brackish water supplies when utilized in deluge systems. The external corrosion resistance of the RILSAN coating permits the use of the DV-5 in corrosive atmospheres associated with many types of industrial processing plants and outdoor installations.
