Abstract
An aircraft water heating tank air vent valve includes an air vent valve housing having an upper vent valve body and a lower valve adapter sealingly mated together to define an interior chamber. A tubular collar is disposed within the interior chamber between an upper planar valve seat member and a lower notched valve seat member, and a ball float is movable within the tubular collar between first and second positions seated on the upper planar valve seat member or the lower notched valve seat member, respectively. The lower notched valve seat member includes oblique notches and frustoconical projections providing upper shoulders upon which the tubular collar is positioned, and providing outwardly flaring radially inner oblique edges upon which the ball float can be seated.
