Abstract
The valve passes incoming pressurized fluid through a pair of orifices arranged in opposite side walls of a hollow tubular plug to form two fluid jets which impinge upon one another in the plug interior prior to exiting. The orifices are elongated and selectively covered by an adjustable sleeve which is positioned by manipulation of a valve stem extending outwardly of the valve housing. Further pairs of orifices are angularly arranged with respect to the first pair and the sleeve includes parts which cover the other orifices when a first pair are operative. The valve stem is selectively rotatable to position the sleeve to expose another pair of orifices to the pressurized fluid.
