A valve arrangement (1), e.g. for the use in a park brake system of a commercial vehicle or trailer, comprises:a differential piston (2), comprising a first section (2a) and a second section (2b),wherein the second section (2b) has a smaller diameter compared to the first section (2a), wherein there is a fluidic connection (3) between the first section (2a) and the second section (2b),a housing (4) with a bore (5), in which the differential piston (2) is adapted to move, wherein the bore (5) has at least two sections (5a, 5b), wherein the first section (5a) corresponds to the diameter of the first section (2a) of the differential piston, and the second section (5b) corresponds to the diameter of the second section (2b) of the differential piston, wherein a step (5c) is formed between the first section (5a) and second section (5b) of the bore (5),wherein a first passage (6) and a second passage (7) are arranged and axially spaced in the bore (5), and a third passage (8) is arranged in or next to the second section (5b) of the bore (5),wherein when the differential piston (2) is in a first end position, the second section (2b) of the differential piston (2) rests against the step (5c), and a connection of the first passage (6) and the second passage (7) within the bore (5) is provided,and wherein when the differential piston (2) is in a second end position, a connection of the first passage (6) and the second passage (7) within the bore (5) is blocked.
