Abstract

A ball design for withstanding high differential pressures without leakage features a circumferential groove near the circle of contact on the ball with a surrounding seat. High differential forces are transmitted beyond the circle of contact so that deflection due to applied differential pressures results in flexing in the groove area while maintaining full circumferential seat contact to prevent leakage.
