<p>A fluid control valve includes a valve body having a fluid passageway, a cage mounted in the fluid passageway, the cage including a wall defining a cage bore having an axis, and a valve plug assembly including a valve plug that is axially slidable in the cage bore. The cage defines one or more windows and a valve seat. Each of the one or more windows includes a plurality of slots each having a longitudinal axis. The longitudinal axis of each of the slots is parallel to or tilted at a relatively small angle with respect to a reference plane that is perpendicular to the cage bore axis. The longitudinal axes of the slots are preferably oriented at an angle of about 0° to 15° with respect to the reference plane.</p> |
