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.

Figure 00000001
A pilot operated pneumatic directional valve (10) is proposed, which is characterized in particular by simplified installation and start-up. The pilot control of the directional control valve (10) can be controlled by system pressure or external pressure, without structural measures having to be carried out to guide the pressure medium in a pilot control device (22) or to seal a pilot control channel (32, 34) that is not required. For this purpose, the directional control valve (10) is equipped with a shuttle valve (30), which independently closes the pilot control channel (32, 34) that is not required, regardless of the contacting and control pressure supply, and at the same time connects the pilot control channel (32, 34) carrying the control pressure with the Pilot control device (22).
