ABSTRACT:
A self-venting drain valve is disclosed preferably used in connection with tapping accumulated water at the bottom of a fuel/water separator. A valve having a first portion (14) residing at the bottom of a vessel (10) has a main passage (34) and a secondary passage (26), the secondary passage being provided to allow air to enter the container to eliminate a vapor-lock. A second portion (16) of the valve is threaded on the first portion (14) and forms seals (52, 48, 44). When the second portion (16) is unscrewed, the seals are broken in sequence as follows: 48, 52, 44. Accumulated water as well as some fuel will then pass through the same outlet aperture (76) to a collection container held by the operator of the valve.
