Beschreibung
Zusammenfassung:	The valve i.e. proportional valve (1) has a nozzle body (2) provided with a passage opening (3), and closing element (4) that opens and closes the passage opening. A sealing element (5) is arranged to seal the passage opening, where the sealing element is a separate component, and the sealing element is arranged in a form-fitting manner. The sealing element is arranged with backlash in an axial direction of the valve, where the sealing element is a sealing disk or an O-ring, and the sealing element is arranged at the closing element. Die Erfindung betrifft ein Ventil, insbesondere Proportionalventil oder Taktventil, zum Steuern eines gasförmigen Mediums, insbesondere Wasserstoff, umfassend einen Düsenkörper (2) mit wenigstens einer Durchlassöffnung (3), ein Schließelement (4), welches die Durchlassöffnung (3) freigibt und verschließt, und ein Dichtelement (5) zur Abdichtung der Durchlassöffnung (3), wobei das Dichtelement ein separates Bauteil ist, und wobei das Dichtelement (5) formschlüssig angeordnet ist.
