We deliver a comprehensive package of Deluge Valve (DV)such as the DDX DV, DDX-SS DV with a short delivery time. DDX DV is a hydraulically operated, latching clapper-type valve used to control the water supply to a deluge or preaction system for more information see below Bulletin 518 Rev A and 519 Rev A. DDX-SS DV same specification as DDX DV but then executed in Bronze or Stainless steel for more information see below Bulletin 516 Rev B and 517 Rev C. Diaphragm DV (DDV) utilises a Kevlar® reinforced hemispherical rubber diaphragm to hold back water when the valve is in stand-by mode. The diaphragm has been specifically designed for a high level of endurance, coping with working pressures up to 400psi. Diaphragm DV provides one of the lowest hydraulic friction loss values for diaphragm type valves in the industry.
