1. A valve for pressure compensation and/or for emergency venting of a container, the valve comprising:
a housing comprising a first end and an inlet arranged at the first end, wherein the inlet is configured to be closed by at least one valve element, wherein the at least one valve element is subjected to a closing force in a first position, and wherein the at least one valve element is at least partially gas-permeable;
the housing further comprising at least one outlet located behind the at least one valve element when the at least one valve element assumes the first position;
wherein the at least one valve element is configured to be adjusted in a direction toward a second position against the closing force when an increased pressure surpassing the closing force exists at the inlet;
wherein, in the second position, the at least one valve element at least partially opens the at least one outlet such that the at least one outlet is directly connected in flow communication with the inlet;
wherein the housing comprises a radially outwardly extending annular flange arranged at the first end;
at least one sealing element arranged at the radially outwardly extending annular flange at a side of the radially outwardly extending annular flange facing a second end of the housing arranged opposite the first end, wherein the at least one sealing element covers at least partially the side of the radially outwardly extending annular flange facing the second end of the housing.
