A spherical shaped device that may be of solid or hollow construction. It is designed to seat in an opening thereby preventing the passage of fluid. It may be used with a spring enabling the ball to become unseated at a predetermined pressure as exerted by the fluid flow and to become reseated in the absence of fluid pressure.
