BOTTOM OPERABLE AIR INLET AND OUTLET VALVE Gunter R. Behle St. Charles, Missouri Abstract of the Disclosure An air inlet and outlet valve is located in the bottom of a tank so that the operator need not climb to the top of the tank to operate the valve. A conduit extends from the valve to the top of the tank. A stilling well is mounted inside the top of the tank. A ball which is lighter than the lading is mounted in the stilling well. The stilling well includes openings allowing air to enter or leave the tank through the conduit when the ball is in an unseated position in the stilling well. Lading contacting the ball moves the ball into a seated position which blocks the entrance to the conduit and prevents lading from entering the conduit, going down through the conduit to the valve at the bottom of the tank, and discharging from the conduit when the operator opens the valve.
