ABSTRACT:
This invention relates to a butterfly valve comprising a floating disc wherein the seating pressure between the valve seat and the rim of the floating disc is relieved prior to the rotation of the disc for opening and closing, and the seating pressure is established after the disc is rotated to the fully closed position. The floating disc butterfly valves taught by this invention comprise a floating disc mechanically connected either to a valve stem supported at both ends or to double cantilever valve stems. A small amount of the axial movement of the valve stem results in either the establishment or relief of the seating pressure between the rim of the floating disc and the valve seat disposed in the valve body.
