Abstract
An example trim installable in a fluid control valve includes a honeycomb array. The honeycomb array includes mesh walls surrounding elongated paths between opposing ends of the honeycomb array. The trim also includes a nonpermeable structure surrounding longitudinal sides of the honeycomb array, the nonpermeable structure having openings at the opposing ends of the honeycomb array.
Claims20
A flow control trim comprising:
- a honeycomb array including mesh walls surrounding elongated paths between opposing ends of the honeycomb array, the mesh walls including:
- a first mesh wall between a first elongated path and a second elongated path of the elongated paths, the first mesh wall having first apertures;
- and
- a second mesh wall between the second elongated path and a third elongated path of the elongated paths, the second mesh wall having second apertures, the first apertures being larger than the second apertures;
- and
- a nonpermeable structure surrounding longitudinal sides of the honeycomb array, the nonpermeable structure having openings at the opposing ends of the honeycomb array.

A valve assembly comprising:
- a valve body including an inlet and an outlet;
- a flow control trim rotatably coupled to the valve body, the flow control trim including:
- a spherically-contoured housing;
- and
- a cellular array fixedly coupled to the spherically-contoured housing, the cellular array including a plurality of elongated passageways along a length of the cellular array, the elongated passageways including:
- a first mesh structure extending along the length of the cellular array, the first mesh structure between a first elongated passageway and a second elongated passageway of the elongated passageways;
- and
- a second mesh structure along the length of the cellular array, the second mesh structure between the second elongated passageway and a third elongated passageway of the elongated passageways, the first mesh structure including first apertures that are larger than second apertures of the second mesh structure.

A flow control trim comprising:
- a first mesh wall between a first elongated path and a second elongated path;
- a second mesh wall between the second elongated path and a third elongated path;
- first rhomboid apertures in the first mesh wall;
- and
- second rhomboid apertures in the second mesh wall, the first rhomboid apertures being differently sized relative to the second rhomboid apertures.
