A valve for filling and drawing off liquefied gas bottles, comprises a valve housing and a valve plug. The valve housing comprises a tubular top section (3) which provides a mouth (4) and a flow passage (5) for vaporized liquefied gas, and the valve plug (2) is axially movable through the tubular top section (3) between an open and a closed position of the valve. The tubular top section (3) has a radially inwardly protruding annular rim (6) allowing a narrow passage for the axially movable valve plug (2), and the valve plug has a cylindrical wall side (7) extending upstream to a radially outwardly protruding annular bottom edge member (8). In closed position of the valve said bottom edge member (8) as a stop member is forced against said rim. An elastic annular outlet sealing member (9) is arranged adjacent to said rim, and an elastic annular connector sealing member (10) is arranged between said outlet sealing member and the mouth in a recess (11) in the flow passage of the tubular top section. Said connector sealing member (10) leaves a narrow annular spacing (12) between the cylindrical wall side (7) of the valve plug and said connector sealing member (10). <IMAGE>
