Abstract
To easily control flexographic printing ink of different colors, and washing liquid, to a plurality of printing plates on a plurality of printing stations of a system, a valve housing (26) is formed with a plurality of connection ducts, each coupled to a respective ink and washing fluid supply line. A plurality of elongated plug valve elements (41) are located in bores of the housing, the valve elements having axial bores and axially and circumferentially offset radial bores, leaving a portion of the plug elements solid to form an OFF position. The radial bores can be aligned, upon rotation of the valve elements, with coupling ducts which, in turn, connect with second fluid connection ducts (27-30, 31). Selectively, flow connection between selected supply lines and selected receiving lines are established by a fluid path: second fluid connection ducts (27-30, 31), a selected radial bore (45-48, 49) in the valve element, through a coupling duct (40) in alignment with the selected radial bore, the axial bore (44) of the valve element and one of the first connection ducts (36-39).
