Claim Text:
1. A method of controlling a flow of fluid through a balanced globe valve assembly, the method comprising: moving a valve member disposed within a cage of a housing of the balanced globe valve assembly between an open position in which the valve member is spaced from a valve seat formed in the cage and a closed position in which the valve member is seated within the valve seat so that the valve member blocks at least one port formed in the cage; and balancing fluid pressure on opposite surfaces of the valve member through an opening in the valve member; wherein the valve member includes a solid body having a top surface and a bottom surface, the top surface being planar and having a top surface diameter measured about a top surface center; wherein the opening extends from the top surface to the bottom surface; wherein the opening has an opening diameter that is smaller than the top surface diameter and that has an opening center that is radially offset from the top surface center; and wherein the bottom surface has a bottom surface diameter that extends radially outward of a rubber seal supported on the valve seat, the bottom surface having a horizontally extending portion that engages the rubber seal when the valve member is in the closed position.
