A valve fitting for a keg includes a valve body 5, a valve for permitting/preventing flow of fluid through a fluid conduit and a connection formation 50 for engagement with a corresponding formation on a keg. At least one filling aperture 15 is provided in the valve body and at least one release aperture/passage 14a is provided in the valve body. The release aperture allows gas to pass therethough while the valve body is partially engaged with the corresponding formation on the keg. Preferably the formations are in the form of threads. In other aspects the release aperture is positioned closer to a valve entrance than the filling aperture. In another aspect the release aperture is at least partially formed in the connection formation of the valve body. Another aspect relates to a keg which includes a formation which allows gas to exit the keg while the formation on the keg is partially engaged with a connection formation on a valve body. |
