The Rhinoflex duckbill check valves are an
exceedingly reliable and an excellent, affordable
alternative to flap-gate
valves along with other
check valves. The simple
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 of many
ways , non-return check valves, produced from a variety of
elastomeric rubbers, and built as per the
application as well as the line
pressure and back pressure concerned. They are available in all standard pipe sizes, and
typical application is back flow prevention and
downstream of a 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 low as One inch of head pressure try to 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 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 can handle well water volumes and weights preventing backflow very reliably and consistently, without having maintenance in any way.
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 be utilized in the back flow prevention of Effluent ,Sewage, and Sewerage systems.
The duckbill check valves are successfully used 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.
