CONTROL ELEMENT FOR A BALL VALVE

摘要

A control element for a fluid valve includes a main body having a rounded outer surface on a first side, an inner base surface and first and second opposed inner side surfaces adjacent the inner base surface on a second side. First and second ears are joined to the main body at spaced locations and extend away from the main body on the second side thereof. The ears include opposed inner surfaces adjacent the inner side surfaces of the main body. The inner surfaces together form opposed passage surfaces which diverge from one another at first and second ends to improve flow efficiency.
