Technical Parameters:

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.

d) Anti-corrosion, aging resistance, no deformation, strong adaptability, long service life;
e) Wide range of sizes, nominal diameters DN50 to DN3000
