Abstract
Nested concentric sleeves or tubes subdivide flow of fluids through a fluid control valve into a myriad of streams between the valve inlet and outlet which flow through passages that create a high energy loss and pressure drop on the fluid to release the fluid at low pressures without generating noise, permitting cavitation or eroding equipment through which the fluid flows.
