Pressure Reducing Valve for Water System01.DescriptionPressure Reducing Valve automatically reduces a higher inlet pressure to a steady lower downstream pressure, regardless of changing flow rate and/or varying inlet pressure. The valve is an accurate, pilot-operated regulator capable of holding downstream pressure to a re-determined limit. When downstream pressure exceeds the pressure setting of the control pilot, the main valve and pilot valve close drip-tight.02.Main parts&materialNo.PartMaterialChina stardard1BodyDuctile ironQT450-102BonnetDuctile ironQT450-103Seat ringStainless steelZG1Cr18Ni94YokeDuctile ironQT450-105StemStainless steel20Cr136SpringStainless steel1Cr18Ni97DiaphragmRubberNBR+Reinforced nylon8Ball seatRubberNBR9Pipe fittingBrassHPb59-110Float switchStainless steel0Cr18Ni903.Features001.Stem diaphragm assembly with double lead action through top and seat rings provides long life and reliability.002.All cast iron parts are coated with powder epoxy resin to resist corrosion.003.During maintenance, the main valve can be repaired directly on line without disconnecting from the pipeline.004.The linear flow of valve body is convenient to obtain better control characteristics and lower head loss.005.High strength and light weight of ball iron valve body.006.Reinforced nylon membrane, die layer thickness uniform strength, good precision, durable.007.Internal use of stainless steel seat, guide platen and shaft, durable.008.Good closing effect and zero leakage safety.009.Hydraulic operation does not need external power, can be matched with the need to match different guide valves and accessories as opening and closing or adjust the water level, pressure and flow.Feature description:001.When the water level of the pool reaches full.The main valve is closed by means of a control ball valve.002.When the water level of the pool decreases, the control ball valve begins to fill, then the main valve is opened through the control ball valve.003.Control the ball according to the requirements of the site, directly put the whole set of valve devices together, directly open and close the main valve or separately install the control ball valve at the full water level to achieve the purpose of remote control.04.DimensionsDimensions(mm)DNLØDØKHN-ØdØBPN10PN16PN25PN10PN16PN25PN10PN16PN25PN10PN16PN25502301651651651251251251774-Ø194-0194-019Ø99Ø99Ø99652901851851851451451452024-Ø194-0198-019Ø118Ø118Ø118803102002002001601601602198-Ø198-Ø198-019Ø132Ø132Ø1321003502202202351801801902438-Ø198-Ø198-Ø23Ø156Ø156Ø1561254002502502702102102202438-Ø198-Ø198-Ø28Ø156Ø156Ø1561504802852853002402402503338-Ø238-Ø238-Ø28Ø211Ø211Ø2112006003403403602952953104288-Ø2312-Ø2312-Ø28Ø266Ø266Ø27425073040540542535035537047812-Ø2312-Ø2812-Ø31Ø319Ø319Ø33030085046046048540041043053812-Ø2312-Ø2816-Ø31Ø370Ø370Ø389*35098052052055546047049055016-Ø2316-Ø2816-Ø34Ø429Ø429Ø448NOTE:1.*DN 125/350 use same internal as DN100/3002.AISI 304 factory standard material, consult factory for AISI 316 material05.Execution standardDesign standardCJ/T219, JB/T10674Flange connection standardGB/T17241.6Face spacing standardGB/T12221Inspection testing standardGB/T1392706.Technical parametersNominal diameterDN50~DN600 (2"~24")Nominal pressurePN10/16Operating temperature0°C~85°CSeal test1.1PNShell test1.5PNSuitable mediumWater07.Operating principleThe remote control float valve has the hydraulic control main valve and the float ball switch composition, installs in the pool or the overhead water tower entrance place.When the liquid level of the pool or the elevated water tower reaches the set height, the float switch is in the closed position to close the main valve and stop the water supply to the pool or the elevated water tower;When the liquid level in the pool or the elevated water tower decreases, the float switch opens and the main valve opens one after another to fill the pool or the elevated water tower and realize automatic water replenishment.Precise liquid level control, free from water pressure interference;08.ApplicationsWater plant, secondary water supply, municipal pipe network, reservoir, garbage treatment plant, subway and other industries in municipal engineering;Petrochemical, steel plant, power plant, shipbuilding and papermaking, biopharmaceutical, etc.2.Factory tour3.FAQQ1.How about your delivery time?A.
