  • The Rhinoflex duckbill check valves are a very reliable and a very good, cost-effective option to flap-gate valves and other check valves. The simple one-piece design and reinforced rubber construction get rid of the mechanical and metal components that rust and seize in conventional flap-gates. They're made to order, one of the ways , non-return check valves, made from a variety of elastomeric rubbers, and built as reported by the application as well as the line pressure and back pressure concerned. They are available in all standard pipe sizes, and typical application is back flow prevention and downstream of an pump, at pump stations.

     The Rhinoflex Duckbill Check valves are passive-reactive devices requiring no external mechanisms or power source to function. The Duckbill Check Valve is generally closed and can react and open with as few as 1 inch of head pressure and always provide maximum flow with minimal pressure drop across the valve. This ease of 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 will even seal around trapped solids with as few as 1 psi of back pressure.

    Ideally, the conical concentric design enables the most effective flow hydraulics, and lowest pressure drops. It may handle quite well water volumes and weights and prevent backflow very reliably and consistently, with no maintenance in any respect.

    Typical applications are for Open Launch of flood control, water-waste water, storm water, flood water, in to a manhole, bubble-pit, pond, lake, dam, or sea.
    They may also provide from the back flow prevention of Effluent ,Sewage, and Sewerage systems.
    The duckbill check valves are used with 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.
