A fluid valve controls the delivery of fluid through a passageway by employing a novel valve construction in which a channel within the passageway is adjusted both in size and configuration. A resilient, flexible valve element defines the channel, and the valve element may be adjustably and incrementally compressed to obtain a gradual restriction in the passageway. By adjusting the size of the channel the rate of fluid flow may be controlled. The fluid valve may be used, for example, to control the amount of dampening fluid supplied to the ink roll or offset plate on the plate cylinder of an offset printing press, and will find application in any fluid delivery system where precise control of fluid flow is crucial.
