    • A valve assembly includes a valve body having a body recess and a bonnet including a bonnet recess having a bonnet mating surface. The valve assembly further includes a valve cage disposed within an interior of the valve body, the valve cage including a body portion extending along a longitudinal axis and a circumferential mating protrusion extending from an outer surface in a transverse direction, the mating protrusion including an upper mating surface and a lower mating surface. The upper mating surface is disposed within the bonnet recess to be aligned with the bonnet mating surface, and the lower mating surface is disposed within the body recess to be aligned with the body mating surface, wherein the upper and lower mating surface are not parallel. Accordingly, clamping forces acting on the mating protrusion include a longitudinal and tangential component, allowing for increased clamping forces without plastically deforming the mating protrusion.
