BUTTERFLY VALVE AND METHOD OF MAKING SAME ABSTRACT OF THE DISCLOSURE The invention provides a means whereby a body such as that of a butterfly valve can be prepared with minimal machining. The manufacture of a butterfly valve is described in which the stem openings for the valve are left in their as-cast condition, the stem bushings inserted, aligned with a stem replica and then permanently locked in aligned position by filling the voids between the bushings and the walls of their openings with the same elastomeric compound from which the valve seat is molded. The compound, after curing or setting, being of such thin wall section that for all practi- cal purposes it is a rigid material.
