Zusammenfassung:The invention relates to an electromagnetically actuatable gas valve for metering a gaseous fuel into a suction tract of a motor, in particular a gas or diesel gas motor, comprising a valve seat (1) which is designed as a flat seat and which has multiple annular webs (3) that are arranged in a concentric manner and are connected via at least one radially running web (4) in order to delimit circular or semicircular through-flow openings (2). The electromagnetically actuatable gas valve further comprises a movable valve plate (5) which sealingly interacts with the valve seat (1) and which has multiple annular sealing webs (6) that are arranged in a concentric manner and can be brought into an overlapping arrangement with the circular or semicircular through-flow openings (2) of the valve seat (1). According to the invention, the rigidity of the valve seat (1) and/or the valve plate (5) is substantially constant in the radial direction, the rigidity of the valve seat (1) being greater than the rigidity of the valve plate (5). The invention further relates to a method for increasing the seal of an electromagnetically actuatable gas valve.
