Abstract

Es wird ein vorgesteuertes pneumatisches Wegeventil (10) vorgeschlagen, das sich insbesondere durch eine vereinfachte Montage und Inbetriebnahme auszeichnet. Die Vorsteuerung des Wegeventils (10) kann systemdruckgesteuert oder fremddruckgesteuert erfolgen, ohne daß zur Druckmittelführung in einer Vorsteuereinrichtung (22) oder zur Abdichtung eines nicht benötigten Vorsteuerkanals (32, 34) bauliche Maßnahmen vorgenommen werden müssen. Das Wegeventil (10) ist hierzu mit einem Wechselventil (30) ausgestattet, das unabhängig von der Kontaktierung und der Steuerdruckversorgung selbsttätig den nicht benötigten Vorsteuerkanal (32, 34) verschließt und gleichzeitig eine Verbindung des den Steuerdruck führenden Vorsteuerkanals (32, 34) mit der Vorsteuereinrichtung (22) vornimmt.
