The Rhinoflex duckbill check valves are an extremely reliable and a very good, cost effective option
to flap-gate valves along with 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 made to order, one way , non-return check valves,
produced from various elastomeric rubbers, and built as per the application and the line pressure
and back pressure concerned. They come in all standard pipe sizes, and typical application has
returned 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 supply to operate. The Duckbill Check Valve is usually closed and definitely
will react and open with as few as 1 " of head pressure try to provide maximum flow with minimal
pressure drop throughout 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 provides for the best flow hydraulics, and lowest pressure
drops. These may handle very well water volumes and weights which will help prevent backflow
very reliably and consistently, without any maintenance in any way.
Typical applications are suitable for Open Relieve flood control, water-waste water, storm water,
flood water, in to a manhole, bubble-pit, pond, lake, dam, or sea.
Glowing be utilized within the back flow protection against Effluent ,Sewage, and Sewerage
The duckbill check valves are successfully used in sub-sea applications for example outfall diffuser
systems, along with AIR Aeration, in SPARGE diffusers in Effluent Mixing tanks and slurry mixing
