Abstract
A dry-break discharge valve assembly for use in connection with liquid bulk containers which includes a valve and a valve housing. The valve housing includes an inner lining member having an upper valve seat, and a lower shoulder portion. The valve is movable between a closed position in the housing seated on the valve seat, and an upwardly moved open position. The valve has a stem with a lower portion which is secured by a retaining pin to a retaining member and a spring is disposed within the housing between the shoulder portion and the retaining member so as to urge the valve toward its seated position, thereby creating a leak-proof seal. The valve may be opened by directing an upward force against the lower portion of the valve stem and urging the valve upwardly away from the valve seat. Wings or fins on the valve stem engage the lining member to guide the up and down movement of the valve.
