A valve device (22) is described, comprising a housing (30), a flow duct (38) and a valve body (36) which is arranged in the flow duct (38) and has a sealing section (34) that bears against a housing-side sealing seat (32) when the valve device (22) is closed, wherein the sealing section (34) and the sealing seat (32) together form a sealing region (42), wherein there is a collapse zone (44) immediately upstream of the sealing region (42) in the flow duct (38) when the valve device (22) is closed, which collapse zone (44) is delimited by a boundary wall (48) that is at least substantially perpendicular with respect to a movement axis (50) of the valve body (36) and by a deflector wall (46) that is arranged at an angle with respect to the boundary wall (48), the boundary wall (48) being longer than the deflector wall (46). |
