Duckbill check valve water flood diffuser

Duckbill check valve water flood diffuser

The Rhinoflex duckbill check valves are an extremely reliable and an excellent, economical option to flap-gate valves and also 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 custom made, one way , non-return check valves, made out of various 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 the pump, at pump stations.

 The Rhinoflex Duckbill Check valves are passive-reactive devices requiring no external mechanisms or source of energy to operate. The Duckbill Check Valve is usually closed and definitely will react and open with as little as 1 inch of head pressure and always provide maximum flow with minimal pressure drop across 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 can even seal around trapped solids with as little as 1 psi of back pressure.
 
Ideally, the conical concentric design enables the very best flow hydraulics, and lowest pressure drops. It may handle well water volumes and weights which will help prevent backflow very reliably and consistently, without having maintenance at all.
Typical applications are for Open Turmoil flood control, water-waste water, storm water, flood water, in a manhole, bubble-pit, pond, lake, dam, or sea.
They may also supply from the back flow prevention of Effluent ,Sewage, and Sewerage systems.
The duckbill check valves are proven to work in sub-sea applications for example outfall diffuser systems, plus AIR Aeration, in SPARGE diffusers in Effluent Mixing tanks and slurry mixing systems.
