Product Description Forged Metal Seated Ball Valve1.Forged Metal Seated Ball Valve featureforged ball valve,the forging material can ensure sufficient rigidity and strength under maximum rated operation pressure without inherent flaw of cast. Enough wall thikness of separate body and adaptation of high strength tie bolts are convenient for valve maintenance and sufficient to bear the stress of pipe.The internal parts of valve are carefully designed and selected to ensure reliability under all kinds of work condition.2.Anti-fire safe designWhen the trunnion ball valve be used normally,its sealed by seat and ball surface,seat retainer sealed by O-ring and body,this is soft sealed and reliable sealing.When the seat and O-ring are burnt,the seat retainer and body will be sealed by expanded graphite.Thus act anti-fire safe purpose.3.Anti-static deviceIn order to prevent friction among ball,stem and PTFE that generates static electricity which may light the combustibles and explosives that cause an accident,in this ball valve,static-conduction spring is set between the stem and the ball,the stem and the body.Thus static electricity is conducted to ground and system safety is secured.4.Free leakage of body Sealed constructionThe connective position of valve body and bonnet is double sealed by gasket and O-ring,on this base,such factors as fire,high temperature,shock and uneven opening or closing of the torque all can't induce external leakage.5.Low torque in operationThe self-lubricated bearings are installed at the friction of stem,resulting in wear resistance,fiexibilityof operation and low torque.6. Double block&bleed(DBB)When ball is full open or close position,the transmitter substance in center cavity of body can be released by drainage and emptying devices.In addition,the over loaded pressure in the center cavity of valve can be released to low pressure end by self relief seat.7.Emergency sealingCompound injection holes are designed and compound injection valves are installed at locations of stem/cap and body support of side valve.When sealing of stem or seat is damaged to induce leakage,the compound can be used to do the second time sealing.A concealed check valve is installed in side of each compound injection valve to prevent compound from out flowing due to the action of transmitter substance.The top of the compound injection valve is the connector for fast connection with compound injection gun.8.Extension stemFor the underground installed valve,the stem can be lengthened and for the convenience of operation the corresponding compound injection nozzle and drainage valve can be extended to the top of valve.9.Automatic body cavity reliefWhen the body pressure going up un-normally as the unstable factor,the trunnion ball valve downstream seat will be pushed by unnormalpressure,and the release the un-normally pressure automatically,it doesn't damage to the sealing of upstream seat.10.Various driving typesThe top pad of valve designed according to ISO 5211,which is convenient for connection and exchange of various drivers.The common driving types are manual,electrical,pneumatic and pneumatic/hydraulic FORGED STEEL trunnion mounted Ball Valve CLASS 150~1500Bolted cover or welded cover,three-piece Body,fixed BallFull or Reduced bore,Blowout Proof StemFire safe and Anti staticDual seat with injection and drain & outletASTM A105N,A182 F304,A182 F316,A182 F304L,A182 F316LStandards complianceDesign and manufacture: ANSI B16.34,API 608,API 6D,BS5351Face to face dimensions: ANSI B16.10,API 6DFlanged connection: ANSI B16.5Butt welded: ANSI B16.25Fie-safe: API 607~API 6FATest and inspection: API 598,API6D Standard material specificationsPart nameMaterialBodyA105A182 F304A182 F316A182 F304LA182 F316LBody capA105A182 F304A182 F316A182 F304LA182 F316LBallA105+NipA182 F304A182 F316A182 F304LA182 F316LStemA105+NipA182 F304A182 F316A182 F304LA182 F316LSeatA105+NipA182 F304A182 F316A182 F304LA182 F316LSeat ringPTFE/RPTFE/NYLONFixed turnnionA105+NipA182 F304A182 F316A182 F304LA182 F316LO-ringVITONVITONVITONVITONVITONContact spring17-7PH/In conelIn conelIn conelIn conelIn conelCover boltA193 B7A193 B8A193 B8MA193 B8MA193 B8MCover nutA194 2HA194 8A194 8MA194 8MA194 8MBearingSF-1SF-1SF-1SF-1SF-1CLASS 150lb~1500lb FORGED STEEL trunnion mounted Ball ValveDimensions & weightsClass 150lbSizeinch23468101214161820L(RTJ)mm178203229394457533610686762864914Hmm153195213500568605662725770970935H1mm139178191220289318382430470489528L0mm400600850400*400*400*400*800*800*600*500*Weightmm305090203289450588676864764911 Dimensions & weightsClass 300lbSizeinch23468101214161820Lmm216283305403502568648762838914911L(RTJ)mm2322993214195185846647788549301010Hmm153195213500569605662725770970935H1mm139178191220289318382430470489528L0mm60012501300400*400*400*400*800*800*600*500Weightmm305090203289450588676864764911 Dimensions & weightsClass 600lbSizeinch23468101214161820Lmm29235643255966078783888999110921194L(RTJ)mm29535943556266379084189299410951200Hmm1531952135005696457027508159701065H1mm119145180220289318382430470489561L0mm60012501300400*400*457*457*800*800*600*600*Weightmm326412226752177311181700197012181646 Dimensions & weightsClass 900lbSizeinch23468101214161820Lmm3683814576107378389651029113012101321L(RTJ)mm3723844606137808419681038114012321334Hmm16220523959170070082095099010301200H1mm119145180213254327368442483523615L0mm60012501300450*600*750*750*600*600*600*600*Weightmm487813827554784712241676208326943515 Dimensions & weightsClass 1500lbSizeinch23 8101214161820Lmm3684705464699111301257138415371664L(RTJ)mm372473549711841100011461276140715591686Hmm197254291655660735860950106512351275H1mm119145180213278384440442483576615L0mm60012501300760*450*450*660*600*750*750*750*Weightmm559716232866893614081861239232204491
