ABSTRACT:
A ball cock for fluids carrying abrasive materials has its inlet passage terminating with a smaller cross section than the mouth of a ball passage which, in turn, has a smaller cross section than the mouth of the outlet passage aligned therewith. The cross sectional differences exceed manufacturing and assembly tolerances and have been found to minimize wear of the ball cock.
