A valve arrangement for a vibration damper, as may be used on a vehicle. The vibration damper can be a telescopic suspension fork leg of a motorbike, or a shock absorber for a vehicle with more than one track, for example an automobile. The valve arrangement is for a vibration damper that has a valve housing with an annular valve seat, and is configured to receive damping fluid, and further having a valve piston arranged in an axially displaceable manner relative to the valve seat in an inner space of the valve housing. The valve piston has a main valve which has a flexible circular valve disc which can be removed from contact with a contact surface side on the valve seat. The valve disc is arranged on the valve piston by a guide pin, such that it can be moved axially relative to the latter and is guided radially.
