A valve (2) for controlling a fluid flow, in particular a gas flow, comprises a valve seat (3), a valve closing element (8) that can be actuated in the axial direction (9) between a closed position in which the same sealingly rests against the valve seat (3), and an open position in which the same is at a distance from the valve seat (3) and allows a fluid to flow through the valve (2), a guiding element (11) that guides a movement of the valve closing element (8) between the closed position and the open position, and a damping element (22) that presses the valve closing element (8) against an adjoining element (13) in the radial direction (30) and is formed as a single piece along with the guiding element (11).
