  • The Rhinoflex duckbill check valves are a very reliable and an excellent, affordable replacement for flap-gate valves as well as other check valves. The straightforward one-piece design and reinforced rubber construction take away the mechanical and metal components that rust and seize in conventional flap-gates. They are custom made, one of many ways , non-return check valves, produced from various elastomeric rubbers, and built as per the application as well as the line pressure and back pressure concerned. They are available in all standard pipe sizes, and typical application has returned flow prevention and downstream of an pump, at pump stations.

     The Rhinoflex Duckbill Check valves are passive-reactive devices requiring no external mechanisms or automobiles to operate. The Duckbill Check Valve is commonly closed and can react and open with as few as 1 " of head pressure and always provide maximum flow with minimal pressure drop across 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 which enable it to 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. It may handle well water volumes and weights and prevent backflow very reliably and consistently, with no maintenance in any respect.

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