4.Features of High Performance Double Offset Butterfly Valve

1) The outer circumference of the disc and the sealing valve seat of the High performance double offset butterfly valve are processed into a hemispherical surface, and the inner spherical surface of the sealing valve seat is squeezed by the outer spherical surface of the disc to produce elastic deformation to achieve the purpose of closing tightly.
2) High performance double offset butterfly valve usually uses tetrafluoroethylene material as its sealing valve seat, but also can use Jinli sealing valve seat to improve its application in high temperature field.
3) High performance double offset butterfly valve The sealing surface of the butterfly plate and the valve seat is in line contact. If you are in a high-pressure environment, do not choose a metal sealing valve seat.
