a valve seat that defines a flow passage opening;
a movable valve element that is displaceable between a closed position, in which the valve element is in abutting contact with the valve seat and the abutting contact defines an axial abutting point, and at least one open position, in which the valve element is moved from the axial abutting point in an axial actuating direction (A); and
at least one leakage element configured to allow a fluid passage in the closed position;
wherein the valve element has upstream of the gas flow a rotationally symmetrical bowl, which axially protrudes past the valve seat opposite to the axial actuating direction (A) by at least 10% of the longitudinal extent of the valve element.
