Sewage Disposal Belled Rubber Slowly Closing Check Valve

 

 

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.


 

Function of rubber duckbill check valve 

Rubber duckbill valve can prevent flood and water intrusion into the sewers and streets of the basement, to avoid significant 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.
