Abstract
Methods and apparatus are disclosed to reduce noise in valve. An example valve includes a valve body defining an inner cavity that fluidly couples an inlet of the valve and an outlet of the valve, the inner cavity having an inner wall with annular cavities spaced apart from one another along a direction of flow of the valve body, a trim to vary a degree of flow of fluid between the inlet and the outlet, and a screen positioned within the inner cavity, the screen at least partially surrounded by the annular cavities and including a pattern of apertures to disperse sound waves generated when the fluid moves therethrough.
