A valve is described having an inlet, an outlet, a sealing element and a device to generate a magnetic field, whereby the sealing element can be moved at least partially by the device and whereby the sealing element connects the inlet to the outlet in a fluid-conducting manner in that the sealing element lifts off at least partially from a valve seat wherein the sealing element is made at least partially of a foam element that can be deformed by the magnetic field.

A valve includes a housing having an inlet (), an outlet () and a movable sealing member () which allows the inlet () and the outlet () to be connected in fluid communication with each other, the sealing member () having associated therewith effective areas () to which pressure can be applied, and sealing areas (), and the sealing member () further having associated therewith a sealing seat () for sealing the inlet () from the outlet (). In order to provide a valve by which pressure can be relieved in a very short time, the sealing member () has associated therewith a conduit () by which the inlet () and the outlet () can be connected in fluid communication with each other when the sealing member () rests on the sealing seat ().
