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 a spiral design or layout. This flow path can direct flow around a central bore. A plug may reside in this bore. This plug can travel longitudinally to change parameters of flow through the control valve. In one implementation, the spiral design can split flow inside of the cage. This feature can elongate travel of flow without any increase in dimensions of the cage (or the valve trim itself).
