Abstract
A valve assembly for a liquid containing tank or the like, having a vortex breaker within the tank of liquid, and affixed to an external valve. The valve has a discharge port and a valve body with an outer member which allows the flow of liquid and a concentrically-spaced inner member provided with upper and lower seals to prevent the leakage of the liquid and allow uniform closure of the valve. The inner tubular member is movable vertically such as with a screw thread and associated handle, from a closed to an open position to allow flow of the liquid from the tank to a discharge port.
