	Graphite Packings are intended to offer high temperature capability,good chemical resistance and markedly reduced spindle wear.By selecting or combining the many versions of Graphite Packings available.
	Didtek Triple Offset Butterfly Valve top flanges are manufactured in compliance with ISO 5211 and will accept standard mounting yoke designs acco
	Laminated metal+graphite seat enables smoothmating, which makes Didtek valves not only in general application but also in LNG/LPG gas applications. Each individual layer services a uniqueand independent sealing purpose. Along with Tripleoffset design, laminated seatring shows excellent performance and help provide lower operationtorque during opening and closing. Different types of materials are selected for laminated metalplate depending on applications.
	Design Description: - Low friction between seat and disc of valve - “Zero Leakage” Sealing Design - Standard Laminated Resilient Disc Seal to 800°F(427°C) - One Piece Shaft - Low torque enables the compactactuator and a long cycle life - Blow-out proof shaft - Optional stem extension - Optional locking device

  dimentions

Design Characteristic of Triple Eccentric Butterfly Valve 1st offset The rotation axis of disc is moving back from the sealing surfaces of disc. The purpose of this offset is to have a continuous sealing surface on the disc. 2nd offset The rotation axic of disc is relocated from the centerline of the body.The purpose of this offset is to lift the disc quickly off and away from the seat ring of the body. 3rd offset The conical axis, which is extended from the sealing surface of disc,is inclined from the rotation axis of disc. The purpose of this offset is to eliminate friction, galling and wear of sealing surfaces during operations and to provide bubble tight shut-off at high and cryogenic temperatures.

Zero Leakage Sealing Design. Zero leakage benefited from the unique design of the disc element and meticulously machines seat to create a perfectly matched disc and seat fit, this design also ensures that the metal seat and metal laminated sealing never be in contact with each other while the valve is cycling. Contact is made between disc seal and body only as final shut off position is reached.
