The metal-to-metal, sealing valve has non-rubbing design which gives less operating torque and longer service life. Offset 1 First offset is between shaft plane and seat plane, which allows complete sealing contact around the seat. 1 Offset 2 Second offset is a distance by which shaft is displaced from normal to the flow line axis, thereby giving camming effect & reduced rubbing rotation while operating the valve. Offset 3 The seal is a segment taken from cone where apex of the cone is offset (3rd) from the flow line axis, which eliminates rubbing completely. 3 Cone axis 3

6 TriTork Triple Offset Valve Design Features : Low Emission Shaft Seal Metal to Metal 'ZERO' Leakage Externally Retained Blow-Out Proof Design Design Features : Standard Mounting External Indicator for Disc Position Bearing Protection One-Piece Shaft Low Emission Shaft Seal Adjustable shaft packing with multiple graphite rings sandwiched between two anti-extrusion rings control fugitive emission and gives longer packing life. Gland packing with live loading is available as an option. Standard Mounting Bracket top side drilling and shaft connection as per ISO Metal to Metal 'ZERO' leakage Laminated resilient seal ring flexes to give uniform wedging effect and ensures 'ZERO' leakage. Resiliency of seal ring allows small deformation in body for temperature fluctuations without risk of jamming. Seal ring is retained by retainer ring and bolting. Gasket behind seal ring ensures leak proof joint. External Indicator for Disc Position Disc position is accomplished by dimple on shaft. When the dimple is inline with flow axis, disc is open. Integral Stellited Seat Body Duplex SS Laminated Seal Ring Disc Gasket Retainer Ring Disc Bearing Protection Graphite ring encased in bearing ensures protection against ingress of line media in to the bearing surface and thus avoids jamming of shaft. Externally Retained Blow-Out Proof Design Engineered gland design gives shaft blow out proof protection externally, conforming to the requirements of API 609. In addition, two screws provided at the bottom retain the shaft against blowout. One-Piece Shaft One-piece shaft is guided by long bearings, which are placed nearer to disc for close support. Bearings are super finished and nitrided for trouble free life. All portion of the shaft within the pressure boundary exceed in strength compare to the shaft portion outside the pressure boundary by minimum 10%. 6 7
