ABSTRACT The filling valve in a counterpressure filling apparatus for admission of liquids into bottles or other types of containers having open upper ends is provided with a sleeve which can descend toward an empty container below the valve and carries a deformable internal annular sealing element which is movable into sealing engagement with the external surface of the open end to center the container. The sealing element is thereupon acted upon by a gaseous fluid to bear against the external surface and to establish a reliable seal during subsequent or simultaneous admission of a pressurized gaseous fluid which precedes the admission of a metered quantity of liquid whereby the liquid expels the gaseous fluid along the same path which serves for admission of pressurized gaseous fluid into the container.
