Abstract
An attenuator dome for a ball valve includes a body defining an upstream surface and a downstream surface. The body has first and second attenuation sections. The first attenuation section has a single stage with a first plurality of passages extending from the upstream surface to the downstream surface. The second attenuation section has a first stage with a second plurality of passages extending from the upstream surface to a first plenum formed inside the body and a second stage with a third plurality of passages extending from the first plenum to the downstream surface. The single stage of the first attenuation section has first flow area percentage, the first stage of the second attenuation section has a second flow area percentage less than the first flow area percentage, and the second stage has a third flow area percentage greater than the second flow area percentage.
