Abstract
A fluid valve and bin aerator for discharging fluid into a chamber while preventing backflow of fluid through the fluid valve with the fluid valve including a resilient member having a set of annular sealing lips located in concentric alignment and at an angle to a sealing surface to provide lips that will cantilever away from the sealing surface and unseal if the pressure on the interior of the fluid valve is greater than on the exterior of the valve to allow fluid to be discharged from the valve, and will cantilever against the sealing surface if the pressure on the exterior of the valve is greater than the pressure on the inside of the valve to seal the fluid valve and inhibit backflow through the fluid valve.
