ABSTRACT:
A discharge valve assembly for a liquid containing tank includes a hollow valve body having an outer tubular member and a concentrically spaced inner tubular member each being closed at one end by a generally disk shaped end portion. Both inner and outer members have radial apertures therethrough adjacent the closed end portion. A tubular gate member is guidably supported between the inner and outer members for axial and circumferentially movement between closed and open positions. A bung is engagable with the inner member and coacts with the tubular gate member when the gate member is in the fully closed position to lock the tubular gate member in the fully closed position.
