Abstract
PURPOSE: To obtain the valve body of the ball valve high in quality and easy to manufacture by a method wherein the valve body and an operation side valve shaft are molded integrally and simultaneously and a follower side valve shaft is connected after the molding.
CONSTITUTION: In the valve body of the ball valve, the valve body 2 and the driving side valve shaft 3 pivotally operated by a servo motor or the like are formed by integral molding upon casting. The follower side valve shaft 4 is connected to this cast molded form by welding after the cast form is molded. Upon the manufacturing of the valve body, the valve body 2 is molded integrally with the driving side valve shaft 3 located at the upper position of the valve body at first, subsequently, the follower side valve shaft 4 is connected to the connecting part C and welded at the welding section W after the molded form is cast.
