The Rhinoflex duckbill check valves are an
exceedingly reliable and a good, cost effective
option to flap-gate
valves and 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. They
are custom made, one of many
ways , non-return check valves, produced from a variety of
elastomeric rubbers, and built as reported by the
application and also the line
pressure and back pressure concerned. One can choose from all standard pipe sizes, and
typical application has returned flow prevention and
downstream of your 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 often will react and open with less than 1 " of head pressure try to provide maximum flow with minimal pressure drop through the valve. This simple operation reduces standing water in sewer pipes where mosquitoes and also 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 few as 1 psi of back pressure.
Ideally, the conical concentric design permits the very best flow hydraulics, and lowest pressure drops. These could handle quite well water volumes and weights preventing backflow very reliably and consistently, without having maintenance whatsoever.
Typical applications are suitable for Open Relieve flood control, water-waste water, storm water, flood water, into a manhole, bubble-pit, pond, lake, dam, or sea.
Glowing be used 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.
