Abstract
A valve trim that is configured to abate noise in a control valve. These configurations may include a cage with a flow path that has interior and exterior openings. The cage may also have a bore to receive a closure member or 'plug.' This plug can travel longitudinally to change parameters of flow through the control valve. In one implementation, the interior and exterior openings are vertically offset or spaced from another along the axis of the bore. In one implementation, the exterior openings are in a section of the cage that is not normally exposed to flow. This feature can increase density of noise-abating features within given dimensions for the cage (or the valve trim itself). Use of additive manufacturing may be useful (or even necessary) to create these parts within certain design envelopes because these techniques can create the unique flow geometry within a unitary or monolithic body. In this way, the valve trim of the present disclosure can maintain, or even reduce, costs of the control valve, while at the same time it can simply the overall construction of the valve device.
