Perfect solution for conditions in-line where Brass, Aluminum and copper create corrosion conditions that affects or compromises the quality of fluid flowing. Engineered Dynamic Design Called “Max-Flo-Chek” tm. This design allows for maximum flow in-line, when positive moving fluid flow occurs, the ball moves freely to a center cavity away from sealing “O” ring allowing for maximum flow all around the ball with zero fluid resistance. On an instant, negative or reverse fluid flow occurs, fluid pushes ball back into its posi-seal “O” ring for a solid stop. In this innovative dynamic design there are no hinged flaps, pins, screws, springs, diaphragms, rubber to restrict flow, malfunction, break or contaminate. To be used in vertical configuration.
