  • The Rhinoflex duckbill check valves are an extremely reliable and a very good, cost-effective substitute for flap-gate valves as well as other check valves. Be simple one-piece design and reinforced rubber construction eliminate the mechanical and metal components that rust and seize in conventional flap-gates. They're tailor made, one of the ways , non-return check valves, made from many different elastomeric rubbers, and built as per the application and also the line pressure and back pressure concerned. They come in all standard pipe sizes, and typical application is back flow prevention and downstream of your pump, at pump stations.

     The Rhinoflex Duckbill Check valves are passive-reactive devices requiring no external mechanisms or source of energy to function. The Duckbill Check Valve is commonly closed and often will react and open with as low as One inch of head pressure try to provide maximum flow with minimal pressure drop through the valve. This easy operation reduces standing water in sewer pipes where mosquitoes as well as other pests can thrive.

    Their all-flexible construction will pass large objects without blockage yet offers exceptional back flow prevention and can even seal around trapped solids with less than 1 psi of back pressure.

    Ideally, the conical concentric design allows for the very best flow hydraulics, and lowest pressure drops. These may handle quite well water volumes and weights and prevent backflow very reliably and consistently, with no maintenance whatsoever.

    Typical applications are suitable for Open Relieve flood control, water-waste water, storm water, flood water, into a manhole, bubble-pit, pond, lake, dam, or sea.
    They may also supply in the back flow prevention of Effluent ,Sewage, and Sewerage systems.
    The duckbill check valves are used successfully in sub-sea applications such as outfall diffuser systems, plus AIR Aeration, in SPARGE diffusers in Effluent Mixing tanks and slurry mixing systems.
