ABSTRACT:
A double-acting valve for the supply of a pressurized gaseous fluid to a closed container includes a resilient sleeve-shaped pressure valve member co-operating with a seat in a part of the valve housing and forming per se a seat for a non-return valve ball. The pressure valve member is releasably secured at the lower end of the tubing which can be connected with a source of compressed air and is displaceable in a part of the valve housing. When separating the tubing from the pressure valve member all movable elements may be detached from the housing so that an efficient cleaning can be effected.
