ABSTRACT:
A valve assembly for a fluid-containing tank and method of making same are provided wherein such valve assembly is mounted on a saddle fixed to a bottom portion of the tank and such valve assembly comprises a housing structure having a fluid inlet and a fluid outlet defined therein, means for mounting the housing structure against the saddle and within the confines of the tank, and a bottom operable valve member carried by the housing structure and adapted to shut off fluid flow between the inlet and outlet, and wherein the inlet and outlet are defined in the housing structure on a common rectilinear flow axis and the valve member has an opening therethrough which is adapted to be aligned between the inlet and outlet to define the open position of the valve assembly. The valve member once moved to the open position enables substantially free unobstructed flow of fluid through the valve assembly parallel to the axis and with minimum pressure drop to thereby enable a maximum rate of fluid transfer through the valve assembly.
