초록

A volume control insert for a ball valve that is attachable in a fluid passage of the ball valve to provide a predetermined flow condition therethrough. The insert has a convex shape corresponding to an outer surface of a valving member seated in the ball valve, and has a connector disposed on its periphery to attach the insert across the fluid passage. The insert has an elongate slot through it, such as an oblong or parabolic shaped opening, adapted to provide the predetermined flow condition. A plurality of such inserts may be furnished with a ball val...
