One exemplary illustration of a valve system for controlling the charge exchange in an internal combustion engine may include a valve seat ring and a valve. The valve may have a valve seat configured to form a sealing system with the valve seat ring. The entire valve is nitrocarburized, and a nitrocarburized surface layer is formed on the valve. The nitrocarburized surface layer is produced by a nitrocarburizing method in a salt bath.
