A valve includes a fluid inlet passageway coupled to a fluid outlet passageway through an orifice and a valve plug that is moveable with respect to the orifice to vary the rate of fluid flow through the orifice. A seat ring is disposed at the orifice and includes a structural member having three vanes connected in a Y-shaped configuration extending into the fluid inlet passageway adjacent the orifice. The Y-shaped vane configuration prevents disturbances, such as intermittent vortices, from forming within the fluid in the fluid inlet passageway and, thereby, provides a stable rate of fluid flow through the valve.
