The Rhinoflex duckbill check valves are an exceptionally reliable and a very good, affordable option to flap-gate valves as well as other check valves. The straightforward one-piece design and reinforced rubber construction get rid of the mechanical and metal components that rust and seize in conventional flap-gates. These are generally tailor made, a proven way , non-return check valves, created from various elastomeric rubbers, and built as reported by 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 the 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 usually closed and definitely will react and open with as little as 1 inch of head pressure and try to provide maximum flow with minimal pressure drop throughout the valve. This easy 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 may even seal around trapped solids with as low as 1 psi of back pressure.

Ideally, the conical concentric design allows for the very best flow hydraulics, and lowest pressure drops. These may handle extremely well water volumes and weights which will help prevent backflow very reliably and consistently, without having maintenance in any respect.

Typical applications are suitable for Open Discharge of flood control, water-waste water, storm water, flood water, in to a manhole, bubble-pit, pond, lake, dam, or sea.
Glowing supply within the back flow protection against Effluent ,Sewage, and Sewerage systems.
The duckbill check valves are proven to work in sub-sea applications like outfall diffuser systems, along with AIR Aeration, in SPARGE diffusers in Effluent Mixing tanks and slurry mixing systems.
