A valve device for brake control of a different pressure medium-operated vehicle brake systems comprises a housing that has pressure medium ducts. A relay valve provides a pneumatic control pressure, which is fed to the relay valve via at least one of the pressure medium ducts at a higher flow rate. At least one insert is pneumatically connected to at least two of the pressure medium ducts, which can be pneumatically connected to each other by the insert. The two pressure medium ducts define a pressure medium path, the profile of which differs based on the housing that is in each case selected and/or switched based on the selected insert. The housing is selected from a set of housings having different pressure medium ducts, in particular bores, but which are otherwise essentially similar. The insert is selected from a set of different inserts.
