Abstract
A ball valve may include a control element including a perforated screen disposed within the control element and spaced apart from an inner surface of the control element to form an annular space and a plurality of chambers disposed within the control element. When fluid flows through the control element, sound waves pass through the perforated screen and are reflected back by the plurality of chambers to disrupt other sound waves, thereby reducing fluid noise in the rotary valve.
