We’ve always provided a wide range of accessories as part of a fully prefabricated solution, so alongside pumping stations, flow regulators andseparators, we’ve now added duckbill valves to match any application.
Fuller duckbill check valves are an exceptionally reliable and cost effective alternative to flap-gate valves and other conventional check valves. With their simple one-piece design and reinforced rubber construction, they immediately cut out the mechanical and metal components that rust and seize.
They will pass large objects without blockage yet offer exceptional back flow prevention and can even seal around trapped solids with as little as 1 psi of back pressure.
All the valves are passive-reactive devices requiring no external mechanisms or power source to operate. They are also manufactured with top quality materials including an outer layer specially formulated to repel growth of marine organisms.
Available as slip-on, flanged, insertable or in-line, they cover anything from stormwater outfall and flood control systems to effluent discharge and outfall diffuser nozzles.
