Y pattern straight-through flow path,greatly reducing flow resistance. ApplicationApplication.  For valves which size is smaller than 2"(DN50), forged steel valves are recommended. Compared with castings,forged valve offer the advantages of more uniform structure, greater density, higher strength integrity, enhanced dimensional characteristics and closer dimensional tolerances.Owing to so many advantageds,the forged valve can be widely used in the fields of petroleum,natural gas,chemical,power and other industries.  Product DetailsMain Parts and Material. NoPart NameCarbon steelAlloy steelStainless steel1BodyA105NA182 F22A182 F304(L)A182 F316(L)2PistonA276 420A276 304A276 304(L)A276 316(L)3Gasket316+Graphite316+PTFE4BonnetA105A182 F22A182 F304(L)A182 F316(L)5NameplatSS6BoltA193 B7A193 B16A193 B6(M)A193 B8(M)Applicable mediumWater,steam,oil.,etcWater,steam,oil.,etcAcid.,etcApplicable temperature-29~425°C-29~550°C-29~200°CMain External Dimensions and Weight.  NPSRB3/81/23/411 1/41 1/22/SB/ 3/81/23/411 1/41 1/22L9898110120140140170200H(Open)858595105114114132145Weight3.13.03.76.58.58.010.912.5Product ParametersProduct Range.PortFull Port(FP)/Reduced Port(RP)StructureBC(Bolted Cover),WC(Welded Cover),PSC(Pressure Self-sealing Cover)DiscSwing type,Piston type or Ball typeRatingClass 150/ 300/ 600/ 800/ 900/ 1500/ 2500Size Range3/8" to 2"End OptionsFLG, SW(Socket Welded), Threaded(NPT/BSP), BW(Butt Welded)Optional Materials:CARBON STEELA105,LF2STAINLESS STEEL F304,F304L,F316,F316LDUPLEXF51,F55ALLOYF1,F5,F5A,F9,F11,F22View 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
