A valve ball physically configured to minimize rotational forces imparted to the ball by fluid pressure acting thereon in flow throttling positions of the ball. In part, the physical configurations that produce the desired effect include a hollowed out ball interior and recessed areas on the ball outer surface that allow fluid flow past the ball exterior when it is partly open.

Valve ball configuration

A casting system is disclosed which utilizes conventional CAD/CAM software to automatically position the rods of a pin mold to replicate, by the rod end surfaces, the surface contours of an object drawn on a CAD machine when the object is cast in the pin mold. The system modifies the data base to account for the plastic liner and liner variations to permit production of styrofoam cores in the Lost Foam Casting process while the pin mold incorporates a rod and hole configuration in the guide plates which permits automatic positioning and frictional locking of the rods in the pin mold.
