Abstract
A component for a ball valve that is configured to reduce noise. The component or “shoe” can install into the valve body, for example, on a downstream side of a throttling ball. In one implementation, the embodiments comprise an annular ring with an inner surface and an outer surface. The inner surface is cupped to receive a portion of the throttling ball. The outer surface may have a stepped profile with portions of the annular ring that have concentrically-decreasing diameter. This stepped profile sits in a corresponding recess in the valve body. Welds can be used to secure the shoe in place in lieu of fasteners, like bolts or screws.
