Flange Type Water Pressure Reducing Valve

Flange type water pressure reducing valveIntroductionThe pressure-reducing valve is adjusted to reduce the inlet pressure to a desired outlet pressure and rely on the energy of the medium itself to keep the outlet pressure automatically stable. From fluid mechanics point of view, pressure reducing valve is a throttling element, local resistance to change that by changing the throttling area, change the kinetic energy of the flow velocity and fluid, different pressure loss, so as to achieve the goal of decompression. Then the control and adjustment system can be adjusted to balance the pressure fluctuation of the valve and the spring force, so that the pressure of the valve remains constant within a certain margin of error. It is widely used in high rise buildings, water pressure of the city water supply pipe, and other occasions, so as to ensure the proper service water pressure and flow of water points in the water supply system.Specification       No..PartMaterial1BodyCast Iron (GG25, HT200) / Ductile Iron (GG40, QT)2Seat410 S.S. / SS 304 / SS 3163Stem410 S.S. / SS 304 / SS 3164O-ring washerCast Iron5O-ringNBR6O-ringNBR7DiscCast Iron (GG25, HT200) / Ductile Iron (GG40, QT)8DiaphragmRubber9Diaphragm WasherCast Iron10ScrewBronze11SpringSpring steel12CoverCast Iron (GG25, HT200) / Ductile Iron (GG40, QT)13Ball ValveBronze14Ball valveBronze15Pressure show 16Pilot valveBronze17Hang ringSteel18Pilot socketBronze19Needle valveBronze20Ball valveBronze21Pressure show 22StudSteel23ScrewSteel  DN(mm)506580100125150200250300350400450500600L20323528536040045558565080086091598010751230PN10D160180195215245280335390440500565615670780D1125145160180210240295350400460515565620725PN16D160180195215245280335405460520580640705840D1125145160180210240295355410470525585650770PN25D160180195230270300360425485550610660730840D1125145160190220250310370430490550600660770H395405430510560585675730760840910103011351270  PhotoesOur CompanyWe could supply fire hose, fire hose fittings, spray nozzle, coupling, automatic fire sprinkler system products, gate valves, check valves, ball valves, etc. All these products strictly confirming to JIS, API ans BS standards.
