Custom Rubber Raw Materials Rubber Flanged Duckbill Check Valve
With Long Service Life
Duckbill check valve Description:
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.

Characteristics of rubber duckbill check valve:
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
