Abstract

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.
