Abstract: A fluid valve includes a valve body having a fluid inlet and a fluid outlet. A fluid passageway connects the fluid inlet and the fluid outlet. A trim assembly is located within the fluid passageway and the trim assembly cooperates with a control member to control fluid flow through the fluid passageway. The trim assembly includes a cage and a cage retainer. The cage retainer is located downstream of the cage and the cage retainer and the cage are aligned longitudinally within the fluid passageway. The cage retainer includes a side branch resonator array.

Abstract: A control valve has a body having an inlet and outlet, a valve seat between the inlet and outlet, a valve plug, and a cage adjacent the valve seat to provide guidance for the valve plug. The valve plug is movable between a closed position, where the valve plug sealingly engages the valve seat, and an open position, where the valve plug is spaced away from the valve seat. The cage has a solid, unitary circumferential wall having inner and outer surfaces and a plurality of passages formed through the wall. Each passage extends between the inner and outer surfaces and follows an arcuate, non-linear path from the inner surface to the outer surface.

Abstract: A flow stabilizer adapted to be disposed in an outlet passage of a rotary valve includes a main body having an axis, a first end, and a second end. A first shell is disposed at least partially within the main body, and the first shell includes an axis, a first end, and a second end. A second shell is disposed at least partially within the main body and at least partially within the first shell, and the second shell includes an axis, a first end, and a second end. The axis of the first shell is angled relative to the axis of the main body and the axis of the second shell is angled relative to axis of the main body.

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.
