Triple Offset Stainless Steel Triple Eccentric Butterfly Valve With Multi Layer Sealing
TEKO triple eccentric butterfly valve provides zero leakage through non-rubbing 90-degress rotation across a wide range of pressure and temperature conditions. It characterized by compact structure, effective handle and long working life and can be widely used in oil & gas, chemical, petrochemical, power station, metallurgy, textile, food, pharmaceuticals and so on
Face to Face according to API 609
Operating temperature:-200℃ to +750℃
Seal Leakage:Per ANSI Fcl 70-2 ClassⅥ
Triple offset design
The shaft is diverged from centerline of sealing surface.
The shaft is diverged from centerline of the pipeline and valve. These two eccentricities are designed for friction reduction between the valve seat and seal ring when opening and closing the valve.
It makes the valve set completely separated from the seal ring through the geometric shape, during the whole process of opening and closing the valve. The special eccentric combination not only makes use of the cam effect, but also completely eliminates friction. It enables no friction between the valve seat and seal ring on the valve plate, to eliminate possible abrasion and leakage, in the 90°stroke of the valve.
