Carbon Steel Flange
Product Description:
Flanged Duckbill Check Valve is a new type of water supply and
drainage valve product with all-rubber structure, shape of
"duckbill" and function of "forward flow and reverse check". It
according to the force analysis and force calculation, according to
different working conditions, using different design mechanism, the
selection of different rubber formulations, and according to the
special process of production. When the water flows into the water
inlet, the small water pressure can open the valve, the greater the
water pressure, the greater the valve is opened, the greater the
water flow. When working in reverse, the valve port is naturally
closed, the seal is backstop, the greater the back pressure, the
tighter the valve port, the better the sealing effect. It is widely
used in municipal, water conservancy, sewage treatment and other
outlet, to prevent backflow, backflow, is the ideal product to
replace the door.
Function:
Rubber duckbill valve can prevent flood and water intrusion into

losses, prevent the water level rising, flooding into the sewage
treatment plant, drainage pumping station, prevent sewage or the
smell of fluid diffusion, and be ready for drainage
