Abstract

A valve device for influencing a fluid supply of fluid-operated loads, includes a valve module with a valve housing in which valve shafts are formed to accommodate valve cartridges, and further includes valve cartridges located in the valve shafts, wherein each of the valve shafts together with the valve cartridges accommodated therein bounds a pressure chamber connected to an assigned inlet port in a fluidically communicating manner, and wherein each of the valve cartridges includes two electrically selectable valve means which are designed to influence a free flow cross-section between the pressure chamber and an outlet port assigned to the respective valve means.
