Sewage discharge drain EPDM neoprene rubber duckbill check valve

Duckbill valve is specially processed by elastic neoprene and artificial fiber. Its shape is similar to duckbill, so it is called duckbill valve. In the absence of internal pressure, the duckbill outlet is closed under its own elastic effect; as the internal pressure gradually increases, the duckbill outlet gradually increases, keeping the liquid capable of being discharged at a high flow rate. The valve has no moving components and is maintenance-free.

Sewage rubber check valve is mainly used in sewage discharge system, pump outlet lifting pump station and submerged aeration system. All rubber structure, corrosion resistance and long service life. And we provide a tight seal to prevent backfilling and maintenance-free.

Rubber duckbill valve can prevent flood and sewage backflow into street sewers and basements, avoid major losses, and prevent flood backflow into sewage treatment plants and drainage pumping stations when the water level rises; stop the diffusion of sewage or odorous fluid, and drain at any time ; In rainy seasons, it can prevent urban river floods from being poured back into the streets.
