Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the sealing performance for a valve seat, of a proportional valve for controlling a gaseous medium to be used for a vehicle of fuel cell driven type.SOLUTION: The proportional valve for controlling the gaseous medium, especially hydrogen has a seal element 5. The seal element 5 is made from butyl rubber or silicon rubber, especially butyl rubber or silicon rubber including silicon rubber not containing fluorine, or complete butyl rubber or silicon rubber, especially silicon rubber not containing fluorine.
