Custom Rubber Raw Materials Rubber Flanged Duckbill Check Valve With Long Service Life
Duckbill check valve is consist of elastic neoprene rubber and man-made fiber,made by special processing,the shape is similar to the duckbill, so called duckbill valve. Under the condition of no pressure inside, the duck mouth is closed under the action of elastic force,with the increase of internal pressure, the exit of duckbill gradually increases,and the liquid can be discharged at high flow rate.

a) Automatically open and close according to the water pressure difference, safe and reliable, no noise, no personnel operation, no maintenance.
b) The forward opening water resistance is small, the starting pressure is small, and the flow rate is naturally adjusted according to the water pressure:
c) Reverse check seal is good, no leakage, prevent backflow, the greater the back pressure, the better the effect;
d) Anti-corrosion, aging resistance, no deformation, strong adaptability, long service life;
e) Wide range of sizes, nominal diameters DN50 to DN3000
