<p>A filler valve group comprises a device for activating an obturator (12) of a liquid flow pipe (1), which obturator (12) mechanically closes the liquid flow pipe (1) independently of filler machine speed. At the same time a hydraulic closure of the liquid flow pipe (1) is achieved by a filler liquid reaching a prefixed level, whereat the liquid contacts a lower end of a liquid return pipe (19). <IMAGE></p> |
