An electropneumatic valve unit (100, 200) for a vehicle brake system has a plurality of valve sections (102; 104; 106; 108; 204; 206) integrated into a single valve housing (101). The plurality of valve sections (102; 104; 106; 108; 204; 206) includes a front axle redundancy section (102) configured to provide a redundant supply or control pressure for controlling brakes associated with a front axle of a vehicle or a tractor, and a trailer control section (104; 204) for providing supply and/or control pressure to a trailer connected to the tractor. The redundant supply or control pressure for controlling brakes associated with the front axle of the vehicle at the front axle redundancy section (102) is derived from an output pressure of the trailer control section (104; 204).
