Abstract
An improved high performance butterfly is provided. The valve includes a valve body, a disk, an annular seat and a shaft. The disk has at least a portion of the circumference of the peripheral edge notched or beveled to provide better clearance of the annular seat and to reduce wear on the seat. The centerline of the shaft, corresponding to the center of rotation of the disk, is slightly offset from the centerline of the valve.
