ABSTRACT:
A low-noise plug valve is formed with a plug in which one side wall of the plug is a grid defined by a plurality of small openings therethrough, which openings lead from the through passage of the plug to a region outside the plug and which grid is movable into partial flow-blocking relation with respect to the valve body outlet, in partially open positions of the plug. The grid creates a back pressure which suppresses the flashing and the formation of cavitation bubbles. The grid openings, in the partially open position of the plug, are in substantial alignment with the direction of flow.
