A valve device () includes a tank pressure port (), a first pressure port (), a second pressure port (), and a pressure shut-off valve (). The valve is switched between the individual ports (), and has two valve components (). Upon reaching a predefinable pressure cut-off value, the first pressure port () can be connected to the tank pressure port () by the first valve component (). In the event of the fluid pressure being higher at the second pressure port () than at the first pressure port (), the second pressure port () can be separated from the first pressure port () by the second valve component (). Both valve components () are combined to form a tradable structural unit and are integrated in a common valve housing (), preferably making direct contact. A hydraulic system has this valve device.
