Abstract
A ball valve assembly includes a ball having a fluid pathway and a leading edge portion. The ball is configured to rotate between an open position and a closed position, the fluid pathway is configured to align with a fluid passage while the ball is in the open position, and the fluid pathway is configured to be offset from the fluid passage while the ball is in the closed position. Furthermore, the leading edge portion includes a first leading edge configured to cut a line extending through the fluid pathway as the ball rotates from the open position to the closed position, the leading edge portion includes a second leading edge configured to engage a seal of the ball valve assembly as the ball rotates from the open position to the closed position, and the first leading edge is positioned radially inward from the second leading edge.
