Abstract

The invention relates to a valve device for the fluid supply of fluid consumers, comprising several valve modules (2) arranged next to each other in the direction of stacking (3). Said valve modules (2) respectively comprise a plate-shaped channel body (11) provided with a feed channel recess (35) and/or a venting channel recess (36) and four 2/2 distributing valves (41, 42, 45, 46) respectively having a first and a second fluidic connection (47, 48, 49, 50, 51, 52, 55, 56). The four 2/2 distributing valves (41, 42, 45, 46) of the valve module (2) are interconnected in a full bridge arrangement. According to the invention, an additional module (6, 7), which is arranged on the connection surface of the channel body, is connected so it communicates with one or both working channels (21, 22) and is designed to control a fluid flow and/or for determining a parameter of the fluid flow from or to the working channel (21, 22).
