  • The Rhinoflex duckbill check valves are an exceptionally reliable and an excellent, cost effective alternative to flap-gate valves and 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. These are customized, one of many ways , non-return check valves, made out of a number of elastomeric rubbers, and built as per the application and the line pressure and back pressure concerned. One can choose from all standard pipe sizes, and typical application is back flow prevention and downstream of a pump, at pump stations.

     The Rhinoflex Duckbill Check valves are passive-reactive devices requiring no external mechanisms or automobiles to use. The Duckbill Check Valve is normally closed but will react and open with less than 1 inch of head pressure and always provide maximum flow with minimal pressure drop over the valve. This simplicity of operation reduces standing water in sewer pipes where mosquitoes and 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 as few as 1 psi of back pressure.

    Ideally, the conical concentric design provides for the very best flow hydraulics, and lowest pressure drops. It may handle quite well water volumes and weights and stop backflow very reliably and consistently, without having maintenance whatsoever.

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