Abstract
A 3-way T-flow ball drain valve permits the draining/filling/purging of a hydronic or plumbing system at the end of the line. This permits the orientation of a drain port in either horizontal or vertical position while permitting end of line draining. A drain valve member is positioned to permit the opening of the drain port when the T-ball valve member in the tee-shaped valve body has been open to permit flow toward the drain port.
