This valve is designed to open fully when the liquid level reaches a preset low point, and close drip-tight when the level reaches a preset high point. The float pilot is remotely installed inside of reservoir, or integrally installed with main valve for size less than 4 inch. The high and low point can be adjusted on the spot. The max adjustable distance is 0.5m, if need more, consult factory.02.Main parts&materialNo.PartMaterialChina stardard1bodyDuctile ironEN-JS10402Seat ringStainless steelAISI 3043O-ringRubberNBR4O-ringRubberNBR5Screw boltStainless steelA26GasketStainless steelA27bonnetDuctile ironEN-JS10408Shaft SleeveLead BrassCZ 1229SpringStainless steelAISI 30410NutStainless steelA211DiaphragmRubberNBR12Diaphragm pressure plateDuctile ironEN-JS104013Hinge PinStainless steelAISI 30414YokeDuctile ironEN-JS104015Seal RingRubberNBR16Guide plateStainless steelAISI 30417StemStainless steelAISI 304I8PlugStainless steelAISI 30403.Features001.The diaphragm assembly provides long life and reliability with a stem guided by both top and seat rings.002.All cast iron parts are coated with split epoxy resin to resist corrosion.003.During maintenance, the main valve does not need to be removed from the pipeline and can be repaired directly on line.004.The alignment of valve body allows for better control characteristics and lower head loss.005.Ductile iron body has high strength and light weight.006.Reinforced nylon diaphragm, film thickness uniform high strength, good precision, durable.007.Internal use of stainless steel seat, guide platen and shaft, durable.008.Good closing effect, zero leakage safety.009.Hydraulic operation does not need external power, can cooperate with the need to match different guide valves and accessories as opening and closing or adjust the water level, pressure and flow.04.DimensionsDN LBHDPN10PN16PN25N.W. kg5023017323285 4-019 1465290197259954-0194-0198-01919803102242791028-0198-0198-019231003502653051208-0198-0198-023321504803524451528-0238-0238-028682006004365691828-02312-02312-02811225073051861121212-02312-02812-03117830085060065924212-02312-02816-031225DNLØDØK  HN-ØdPN10PN16PN25PN10PN16PN25PN10PN16PN25400110056558062051552555081316-02816-03116-037450110061564067056558560081320-02820-03120-0375CO125067071573062065066096720-02820-03420-0376CO1450780840845725770770114020-03120-03720-0407001450895910960840840875114024-03124-03724-04305.Execution standardDesign standardCJ/T219, JB/T10674Connection standardGB/T17241.6Face spacing standardGB/T12221Inspection testing standardGB/T1392706.Technical parametersNominal diameterDN50~DN600(2"~24") PN10DN50~DN600(2"~24") PN16DN50~DN200(2"~8") PN25Nominal pressure0.1MPa-0.8MPa0.8MPa-1.3MPa1.3MPa-2.0MPaOperating temperature-10°C~85°CSeal test1.1PNShell test1.5PNSuitable mediumWater07.Operating principleFluctuations when the pipeline pressure in normal circumstances, sampling valve tube after Y type filter to wave the upper valve diaphragm, a buffer holes due to the lower part of the diaphragm valve and valve body are interlinked, diaphragm valve at this time due to the fluctuation of pressure equal to there is no pressure difference and fluctuation valve close on lower part of the diaphragm spring force, when the sudden rise in pressure in pipe, rises high, lower part of high pressure pilot valve diaphragm pressure lifts suddenly, when the pressure rises to more than low pressure pilot valve spring pressure, high pressure pilot valve to open, will wave valve diaphragm upper water leakage, pressure fluctuation after the upper valve diaphragm pressure relief to the diaphragm valve spring force to overcome fluctuations, fluctuation valve open, high pressure pilot valve opens,Pressure water relief into the low-pressure guide valve, the low-pressure guide valve due to the spring force will open the low-pressure guide valve, further drain the pressure fluctuation valve diaphragm on the cavity of the water, so that the pressure fluctuation valve as soon as possible to open.When the water pressure in the pipeline falls, the water in the lower part of the high-pressure guide valve diaphragm is not enough to overcome the spring force on the low-pressure guide valve, the high-pressure guide valve closes, the low-pressure guide valve also closes, at this time the upper part of the fluctuation valve diaphragm is full of water, there is no pressure difference on the lower part of the fluctuation valve diaphragm, the fluctuation valve closes the fluctuation valve by the action of the spring force.Since the lower chamber is connected to the pressure in the valve body throu
