Triple offset design

Stainless Steel Triple Offset Butterfly Valve Anti - Leakage With Multi Layer Sealing 0

1st eccentricity

The shaft is diverged from centerline of sealing surface.

 

2nd eccentricity

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.

 

3rd eccentricity

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.
