Abstract
A valve, such as a ball valve, can include a noise attenuation assembly to control fluid expansion through the valve and provide noise abatement. The valve can include a valve body and a valve stem and the noise attenuation assembly can include a flow control body and a trim body. The flow control body can be coupled to the valve stem and the flow control body can be configured to selectively permit fluid flow through the valve body in an axial direction. The trim body can include a plurality of channels to control fluid expansion during fluid flow through the valve body. The trim body can be engaged with the flow control body at first and second mounting structures of the flow control body to secure the trim within a fluid pathway of the flow control body.
