An adjustable cage assembly for a flow control device can include a first cage body and a second cage body. The first cage body can be rotationally fixed relative to the second cage body at a plurality of alignments to provide a flow opening of variable size for adjustable control of fluid flow areas through the adjustable cage assembly.

Adjustable cage assembly for flow control devices

A control valve includes a valve body, a valve seat, and a valve closure member displaceable a closed position and an open position. An attenuation element is provided and includes a plurality of hollow tubes including a first tube, a second tube and a third tube. Each tube includes a flow axis from an open first end to an open second end, and an inner surface defining a flow area and having a cross-sectional shape normal to the flow axis. A second end of the tubes is between the valve closure member and first ends of the tubes along their respective flow axes when the valve closure member is closed. The first tube, the second tube, and the third tube are integrally formed as a single, unitary structure.

Attenuation element for use with valves

A valve assembly including a valve body defining an inlet, an outlet, a fluid flow path, and a chamber. A control element is disposed in the chamber and in the fluid flow path, and is rotatable by a valve stem about a pivot axis between an open position and a closed position. A flow conditioner coupled to the valve body and including a first end, a second end, and a plurality of channels extending between the first end and the second end. The plurality of channels are in flow communication with the fluid flow path of the valve body when the control element is in the open position. A plurality of walls separate the plurality of channels and include a first thickness and a second thickness different than the first thickness.

Flow conditioner for a valve assembly

A control valve includes a valve body, a valve seat, and a valve closure member displaceable a closed position and an open position. An anti-cavitation element is provided and includes a plurality of hollow tubes including a first tube, a second tube and a third tube. Each tube includes a flow axis from an open first end to an open second end, and an inner surface defining a flow area and having a cross-sectional shape normal to the flow axis. A second end of the tubes is between the valve closure member and first ends of the tubes along their respective flow axes when the valve closure member is closed. The first tube, the second tube, and the third tube are integrally formed as a single, unitary structure.
