DVD 400-E Deluge Valves are elastomeric type globe valves that are rolling diaphragm actuated, with an integral, solid, resilient seal. These automatic water control valves are designed for vertical or horizontal installation and are available in diameter sizes from 2” to 12” (DN 50 to DN 300). DVD 400-E Deluge Valve is held closed by system water pressure trapped in the control chamber. When releasing system operates, pressure is released from the control chamber, and the seal disc opens to allow water to flow into the system. The valve body includes a single, full bore seat with unobstructed flow path, free of any in-line ribs, supporting cage, or shafts. The internal design of the valve is based on innovative technology using advanced rubber based materials to achieve a solid, one-piece, elastomeric assembly including flexible fiber reinforced diaphragm, vulcanized with a rugged radial seal disc, and together providing resilient, drip tight sealing. The elastomeric assembly is carefully balanced and peripherally supported to avoid tension and protect the elastomer, resulting in long life and controlled actuatation even under harsh conditions. The elastomeric assembly can be easily removed from the valve body with no need for disassembling the valve from the line.
