Abstract
A check ball valve assembly is used to regulate fluid flow from two separate fluid sources to a single fluid outlet. The assembly utilizes a single check ball alternating between two check ball seats in two separate fluid passages. A check ball guide is installed at the intersection of the separate fluid passages and deflects the check ball from the pressurized passage to the non-pressurized passage to prevent backflow into the fluid source.

A check ball valve assembly for regulating fluid flow from a plurality of fluid pressure sources, the valve assembly comprising:
- a check ball;
- a first fluid passage in communication with a first of the plurality of fluid pressure sources, wherein the first fluid passage includes a check ball seat;
- a second fluid passage in communication with a second of the plurality of fluid pressure sources, wherein the second fluid passage intersects the first fluid passage and includes a check ball seat;
- a third fluid passage in communication with the first and second fluid passages, and wherein the third fluid passage receives fluid flow from one of the first and second fluid passages;
- an intersection fluid passage in communication with the first, second and third fluid passages;
- and
- a check ball guide insert including a check ball guide, wherein the check ball guide insert is at least partially disposed within the third fluid passage and the a check ball guide is disposed in the intersection fluid passage.
