a valve plug positioned at least partially within the valve body, the valve plug including a through-passage, the valve plug being rotatable relative to the valve body to selectively alter a flow of fluid along the fluid flow path, wherein the fluid flow path exhibits a varied cross-sectional area along a length of the fluid flow path, wherein the through-passage includes a first opening on a first side of the valve plug, and a second opening on a second side of the valve plug; and
a ramped surface positioned in the fluid flow path of the valve body located outside of the valve plug between a proximal end of the valve plug and the outlet of the valve body providing a transition to the outlet of the valve body; wherein an outlet opening of the outlet has a larger cross-sectional area than a cross-sectional area of the through-passage in the valve plug.
