An electropneumatic valve arrangement is for actuating a parking brake function of an electropneumatic brake system of a commercial vehicle, with a pilot control unit, which modulates a pilot pressure in dependence on an electronic parking brake signal, and which is configured to be self-holding, wherein the pilot pressure can bring about a modulation of a parking brake pressure at least at one spring accumulator connection or can be modulated as such. The valve arrangement also has an emergency release connection with an emergency release path for optionally inputting an emergency release pressure, which brings about the modulation of the parking brake pressure at the at least one spring accumulator connection.
