Patent 11913569 was granted and assigned to Nibco Inc. on February, 2024 by the United States Patent and Trademark Office.
A ball check valve assembly includes a combination ball valve and spring check valve within a valve assembly. The use of union ends on the valve assembly permits the easy removal and replacement of the components of the valve assembly from a plumbing system. An integral bleeder valve allows for the pressure release and drainage of the ball check valve assembly before the union ends are decoupled.
