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.

A pressure valve assembly for the supply of a pressurized gaseous fluid to a closed container, comprising: a valve housing with a valve seat therein; a tubular member guided for axial displacement towards and away from said valve seat and forming a fluid supply channel; a resilient hollow pressure valve member releasably secured to said tubular member by a bulb connection at one end of the tubular member, the resilient valve member forming itself a seat for a non-return check valve; and a spring urging said tubular member with the resilient pressure valve member thereon towards the valve seat in said housing.
