ABSTRACT:
A firefighting nozzle capable of selectively producing only a solid stream, only a fog pattern or a combination of both. The passage for the fog liquid can be opened to a flushing position for flushing debris therefrom. A solid stream sleeve is removably attached to a nozzle body for allowing discharge of solid streams having different diameters. A valve ball having primary and secondary flow passages is movable to positions for supplying liquid therethrough to both solid stream and annular fog supply passages, or to only the annular fog supply passage while closing the solid stream passage.
