The Rhinoflex duckbill check valves are an extremely reliable and a very good, economical replacement for flap-gate valves and 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 made to order, one of the ways , non-return check valves, created from various elastomeric rubbers, and built as reported by the application as well as the line pressure and back pressure concerned. They come 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 source of energy to work. The Duckbill Check Valve is normally closed and can react and open with as little as 1 " of head pressure try to provide maximum flow with minimal pressure drop through the valve. This ease 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 may even seal around trapped solids with as few as 1 psi of back pressure.

Ideally, the conical concentric design permits the best flow hydraulics, and lowest pressure drops. These may handle extremely well water volumes and weights and prevent backflow very reliably and consistently, without maintenance in any way.

Typical applications are for Open Discharge of flood control, water-waste water, storm water, flood water, in a manhole, bubble-pit, pond, lake, dam, or sea.
Like provide in 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, as well as in AIR Aeration, in SPARGE diffusers in Effluent Mixing tanks and slurry mixing systems.
