초록

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.
