The metal-to-metal,bi-directional sealing valve has non-rubbing designwhich gives less operating torque and longer servicelife.Offset 1First offset is between shaft plane and seat plane,which allows complete sealing contact around theseat.Offset 2Second offset is a distance by which shaft is displacedfrom normal to the flow line axis, thereby givingcamming effect & reduced rubbing rotation whileoperating the valve.Offset 3The seal is a segment taken from cone where apex ofthe cone is offset (3rd) from the flow line axis, whicheliminates rubbing completely.3

TriTork Triple Offset ValveDesign Features : Low Emission Shaft Seal | Metal to Metal 'ZERO' LeakageExternally Retained Blow-Out Proof DesignDesign Features : Standard Mounting | External Indicator for Disc PositionBearing Protection | One-Piece ShaftLow Emission Shaft SealAdjustable shaft packing with multiple graphite rings sandwichedbetween two anti-extrusion rings control fugitive emission andgives longer packing life. Gland packing with live loading isavailable as an option.Standard MountingBracket top side drilling and shaft connection as per ISO 5211.Metal to Metal 'ZERO' leakageLaminated resilient seal ring flexes to give uniform wedgingeffect and ensures 'ZERO' leakage. Resiliency of seal ring allowssmall deformation in body for temperature fluctuations withoutrisk of jamming. Seal ring is retained by retainer ring and bolting.Gasket behind seal ring ensures leak proof joint.External Indicator for Disc PositionDisc position is accomplishedby dimple on shaft. When thedimple is inline with flow axis,disc is open.Integral Stellited SeatBodyDuplex SSLaminatedSeal RingDisc GasketRetainer RingDiscBearing ProtectionGraphite ring encased in bearing ensures protection againstingress of line media in to the bearing surface and thus avoidsjamming of shaft.Externally Retained Blow-Out Proof DesignEngineered gland design gives shaft blow out proof protectionexternally, conforming to the requirements of API 609. Inaddition, two screws provided at the bottom retain the shaftagainst blowout.One-Piece ShaftOne-piece shaft is guided by long bearings, which are placednearer to disc for close support. Differential expansion due totemperature is taken care by key connection between shaft &disc. Bearings are super finished and nitrided for trouble freelife. All portion of the shaft within the pressure boundary exceedin strength compare to the shaft portion outside the pressureboundary by minimum 10%.6 7
