Electric Pressure Seal Power Station Gate Valve (GAZ960Y)

Electric Pressure Seal Power Station Gate Valve (GAZ960Y)Product DescriptionBrief intro. The middle part of pressure seal gate valve using pressure self-tightening structure,make sure the valve has good sealing performance under high pressure and high temperature conditions,usually,the sealing ring has two kinds of material,one is low carbon steel,the other is flexible graphite+SS 316,besides,the sealing surface is welding with hard alloy,after the welding is finished,the thickness of metal layer should be 3mm or more,therefore,it has advantages of wear-resistant,temperature-resistant and anti-corrosion,greatly prolong the service life.Both ends adopt welding structure,the dimensions of welding groove can be customized on clients' requirements.The medium can be high temperature and high pressure water,steam,oil products and super-heated steam.,etc,it's widely used for thermal power plant,petrochemical industry,metallurgy and other industrial sectors.Product FeaturesMain Features.The central connection adopt pressure self-tightening structure.The disc and seat are welding with hard alloy.High temperature creep resistance design.The material of stem is precipitation hardening stainless steel by nitriding.Operating device can be manual,gear,bevel gear and electric actuator.Product DetailsMain Parts and Materials.Part NameMaterial MarkBodyWCBWC1WC6WC9DiscWCBWC1WC6WC9Seat2515CrMoA12Cr1MoVA12Cr1MoVAStem1Cr17Ni21Cr17Ni2SUH600SUH60020Cr1Mo1V1A20Cr1Mo1V1ACover2515CrMoA12Cr1MoVA12Cr1MoVAWCBWC1WC6WC9PackingReinforced flexible graphiteYokeWCBWCBWCBWCBWC1WC6WC9Sealing ringMild steel(reinforced flexible graphite)Mild steelMild steelStem Nut45Suitable temp.≤425 °C≤450 °C≤540 °C≤570 °C  Main External Dimensions.PNDNdLHL1L21500LB2 1/2"562547821402433"643057851402434"844069181982819194005555"1004839971982819974005556"126559118241056511954206548"1587111202410565122742065410"2008641488440688145242065412"25099116554206881716440 14"28010671905690 16"31811942048690 18"36013462245690 2300715 20"40614732546690 2621715 22"45016002775690 2871715   Product ParametersPN(Mpa)Test Pressure(Mpa)Working TemperatureApplicable MediumShellSeal10.015.011.0≤425 ºCWater,Steam,Oil.,etc16.024.017.620.030.022.025.037.527.532.048.036.0  View of the factory  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
