Abstract
An improved disc for a butterfly valve having reduced structure within the bore of the valve, so as to minimize obstruction to the flow of granular material therethrough. Accelerated flow of granular material through the valve is obtained because of the thin dimensions of the butterfly valve. The modified disc includes upper and lower sockets, most of its structure is outside the perimeter of the disc. The disc may be of arcuate shape.
