Features & BenefitsTriple-offset GeometryIn Triple-offset Butterfly Valves, the shaft is offset from the sealing surfaceand body centreline. Further the sealing cone is rotated away from thebore centreline to create a third offset.The triple-offset geometry ensures that the body and disc come intocontact only at the final shut-off position. This eliminates wear and teardue to interference, reduces operating torque and enhances product life.Sealing ConeBody CentrelineDisc OpenFirst OffsetThird Offset (Angle)Second Offset8Disc Closed

Features & BenefitsAssured Sealing to AtmosphereTriple-offset Butterfly Valves meet the FugitiveEmission Test requirement of ISO 15848. This isachieved by employing high-integrity graphitegland packing and a gasket between bottomcover and body.Anti-blowout ShaftThe shoulder onthe shaft that bearsagainst the gland,and the thrust plateattached to the shaftmake it blowoutproof.Bi-directional bubble-tight sealingTriple-offset Butterfly Valves are torque-seatedvalves where bubble-tight sealing is achievedwhen the laminar seal flexes and generates acompressive force all around the hard-facedbody seat.Replaceable Metal-to-Metal SeatsThe laminar seal of Triple-offset Butterfly Valvesare designed to be replaceable at site. It is alsopossible to renew the integral hard-faced bodyseat of TOBV by re-depositing Stellite.9

SpecialsRemote-operated Shut-off Valves (ROSOV)Triple-offset Butterfly Valve, an inherently fire-safe valve that providesbi-directional bubble-tight sealing, has emerged as the valve of choice foroil movement and storage application worldwide. With this versatile valveat its core, L&T Valves offers Remote-operated Shut-off Valves (ROSOV)that leverages in-house capabilities in valve automation, and system designand integration.A typical ROSOV is a fail-safe system that comprises pneumatic/ electrohydraulic actuator, and solenoid valves, positioners and accessoriesintegrated on a control panel. The product meets the requirements of IEC61508 and IEC 61511 standards and is designed to enhance operationalsafety and efficiency in oil tankages and terminals.Cryogenic ValvesL&T Valves manufactures a range of cryogenic and low temperature Tripleoffset Butterfly Valves that conforms to BS 6364. The austenitic stainlesssteel valves are designed to perform at temperatures as low as -196 C. Thevalves are offered with extended shaft to ensure that cryogenic line fluidsdo not impair the performance of gland packing.Triple-offset Butterfly Valves are available in ASME classes 150 to 600, in avariety of body styles and end-connections.10

SpecialsFabricated Steel Triple-offset Butterfly Valves for WaterL&T Valves, a pioneer in valves for water service, has introduced aninnovation for the water industry - Fabricated Steel Triple-offset ButterflyValves for Water.The valve is available in sizes up to 100” (2500 mm) in pressure classesfrom PN 6 to PN 25 to suit customer requirement. The valves meet therequirements of AWWA C 504, AWWA C 516, EN 593 and ISO 5752standards.The valve body, fabricated from carbon steel plates, has better mechanicaland structural properties compared to cast iron body. Further, the metalseated valve handles line impurities better than soft-seated valves, andprovides reliable sealing for a longer period.Top-entry Triple-offset Butterfly ValvesL&T Top-entry Triple-offset Butterfly Valve range is the specially designedfor applications that require online maintenance. The top cover providesaccess to valve internals for complete renewal of valve trim - withoutremoving the valve from the line, without jeopardising system safety andoperator life.The valve is available in sizes up to 48” (1200 mm), in ASME classes up to900, with long pattern body and butt-weld ends.11
