A valve device including a valve housing which bounds a valve chamber in which a valve member is accommodated for movement between a blocking position and a release position in order to influence a free flow cross-section for a fluid in a flow path between an inlet passage terminating into the valve chamber and an outlet passage leading from the valve chamber, further including a first absolute pressure sensor for providing a first pressure signal as a function of an operating pressure in the flow path, and further including an evaluation circuit for processing the first pressure signal. It is provided that a second absolute pressure sensor is located outside the flow path, which is designed to provide a second pressure signal as a function of an operating pressure outside the flow path and which is connected to the evaluation circuit for enabling a differential pressure between the first and second pressure signals to be determined.
