Zusammenfassung:	Apparatus to increase the fluid flow in a valve are disclosed. An example apparatus includes a valve body (206) having a fluid passageway, a valve cage (222) located in the passageway and including a wall having an outer surface and an inner surface defining a cage bore (224) with an axis. The wall has at least one flow zone comprising a plurality of through openings (236), each through opening extending between the inner and outer surfaces to define an opening axis extending through the wall and being shaped like a slot. The opening axis is disposed at a non-orthogonal angle with respect to the axis of the cage bore. A valve plug (240) is axially slidable in the cage bore.
