Abstract:
A control valve has a cage disposed within a valve body adjacent a valve seat and proximate a valve plug to provide guidance for the valve plug. The cage includes a solid, unitary circumferential wall with inlet passages adjacent one of an inner surface or an outer surface and outlet passages adjacent the other of the inner and outer surface. An annular cavity is spaced apart from the inner and outer surfaces and is connected to the inlet passages. Intermediate passages are connected to the annular cavity and recovery plenums interconnect the intermediate passages and the outlet passages. The recovery plenums have cross-sectional areas that are larger than a cross-sectional areas of the intermediate and outlet passages.
