Abstract
A method for assembling a rotary ball valve assembly utilizes an axially directed compressive force to urge an annular seal into sealing engagement with a rotatable ball and, while the compressive force is applied, inwardly deforming a tubular member attached to the housing by an electromagnetic force to form an annular abutment retaining said rotatable ball in said tubular member.
