ABSTRACT:
A fluid control valve which avoids wear, cavitation, and high noise level operation and yet is substantially nonclogging. The valve includes a valve nozzle means having at least one preloaded member biased so as to close the valve nozzle means below a preselected incoming fluid pressure. Incoming fluid is spun tangentially within an annular whirl chamber, and then passed through a labyrinth passageway comprising a series of inwardly spaced concentric sleevelike annuli. The concentric sleevelike annuli are so constructed that they may be inserted into a pre-existing plug valve.
