An electropneumatic valve assembly is provided for actuating a parking brake function of an electropneumatic brake system of a commercial vehicle. The assembly includes a parking brake valve unit which receives supply pressure via a supply pressure path. A pneumatically self-holding trailer valve unit is connected to the supply pressure path and has a pneumatically switchable trailer supply valve. The supply valve provides a trailer supply pressure to a trailer supply port in dependence on an electronic trailer brake signal. The parking brake valve unit has a pilot valve unit and a main valve unit and the pilot valve unit outputs a parking brake control pressure at the main valve unit. The main valve unit outputs a parking brake pressure at a spring brake port. The valve assembly has a compensation valve to maintain the parking brake control pressure outputted at the main valve unit to compensate for valve leakage.
