The valve comprises a slide valve (15) for maintaining the vacuum in the upstream section (8) in the absence of a container (9) or in the downstream section (9) while the upstream volume connected to the orifice (4) is not yet under vacuum, a sliding plug (18) to allow filling without the pulverulent material passing through the pipe (19) being able to soil the valve.
