EN 1092-2 Flanged Duckbill Blowdown Check Valve Flexible neoprene
Rubber Check Valve
Product Introduction
Duckbill valve is a unique fluid control device, which is widely
used in modern industrial, agricultural and municipal construction,
with its efficient, reliable and economical advantages to handle a
variety of fluids.
The design and functionality of the duckbill valve makes it a
significant advantage when handling fluids, whether it is sewage
treatment, stormwater drainage systems, or underground parking lot
drainage systems, duckbill valves are effective in preventing the
backflow of sewage or floodwater and protecting infrastructure from
damage.
How it works
The working principle of the duckbill valve is based on its special
design, when the liquid passes through the valve, the shape of the
canap of the valve automatically adjusts the size of the opening
according to the change in flow rate or pressure, ensuring that the
fluid can be discharged smoothly. When the water flow stops, the
duckbill valve closes tightly, preventing liquid or odor from
backing up.
The valve does not require any moving components, is therefore
maintenance-free, and prevents solid particles from jamming and
ensures a tight shut-off.
Product Advantages
· Resilient rubber construction that requires no maintenance and
prevents backfilling.
· It prevents flooding and sewage from backing up into street sewers
and basements, preventing major losses.
· It is a quasi-water seal device, which can isolate the odor of
outdoor inspection wells.
· It is not easy to freeze when opening and closing, and the loss of
opening head is small.
· Long life, good sealing performance, anti-odor back, meet the
requirements of water (air) sealing of indoor drainage ditches and
outdoor drainage pipes.
· In the process of drainage, it can effectively prevent backflow
and sediment formation.
· The diffusion performance is good, the jet speed is fast, the
energy is large, and the discharge port has better diffusion than
other standard round nozzles.
· It has the characteristics of cushioning, sound damping,
maintenance-free and non-corrosion.
