ABSTRACT:
This invention relates to a flange-type stop cock having a ball valve plug. This ball-valve stop cock is so constructed as to have the same profile or outline as the flange portion of the existing flange-type stop cock having a conical-shaped valve plug. The flange mounting holes and the input and the output fluid openings are designed to conform with that of existing pipe seat brackets so that the present ball-shaped plug stop cock is a direct replacement for the conical-shaped plug stop cock.
