Afpumps spherical ball check valves offer extreme reliability whether positioned vertically or horizontally, thanks to their simple construction and absence of mechanisms.
The ball of the valve has a low inertia and therefore the opening pressure of the check valve is about half that of a clapet valve.
Ball coated with nitrile rubber, resistant to clean fresh or sea water, sewage or rainwater even with hydrocarbon residues.
The extreme conceptual simplicity of the valve makes it maintenance-free.
