Zusammenfassung:	A valve comprises a body including a chamber and two superposed closures moving in the chamber and the bottom part of the chamber includes a first seat for one closure and a second seat for the other closure. The closures are each carried by a swing mobile between a position in which the closure bears in sealed fashion on the corresponding seat and a position in which the closure is spaced from the seat. The space between the two closures contains an elastic material membrane closing a chamber into which a compressed air feed discharges. The membrane can therefore be inflated and pressed in sealed fashion onto the top closure to close and seal the inlet of a passage which discharges into a space between the two closures.
