Abstract
A valve assembly, particularly a breather valve assembly for fluid storage tanks, is described. This assembly comprises a valve housing including a fluid conduit and a valve seat defining a fluid outlet of the fluid conduit, and a pressure pallet sized and adapted to move away from the valve seat in response to an increased fluid pressure in the fluid conduit. A seal is provided and acts to effectively seal the fluid outlet against fluid flow from said fluid conduit when the seal is in contact with the valve seat. The seal which includes first and second flexible seal elements which are unsecured to the pressure pallet at or near their respective outer peripheries, is structured so that fluid from the fluid conduit is in the space between the first and second seal elements when the seal means is in contact with the valve seat.
