Abstract
A ball check valve controls the flow of fluid with a sphere. A body has a fluid path and a recess for receiving the sphere in alignment with the fluid path. The sphere has a retainer which secures a ball check within it. When the valve is in a “Run” position and the rate of fluid flow increases, the ball check seats in a narrow opening of the sphere, thus blocking the flow of fluid.
