8 Inch 4 Inch Duckbill Check Valve Wastewater Discharge Flanged Epdm Rubber Non-Return
Industrial Wastewater Discharge Flanged Corrosion And Wear Resistant Epdm Duckbill Rubber Non-Return Valve
Product Description
The duckbill check valve is made of resilient neoprene and artificial fibres, which are specially processed to resemble a duck's beak, hence the name duckbill valve. In the absence of internal pressure, the mouth of the duck closes under the action of elasticity. As the internal pressure increases, the outlet of the duckbill gradually increases and the liquid can be discharged at a high flow rate.
Functionality
Rubber duckbill valves prevent flooding and water intrusion into basement sewers and streets, avoiding major damage, preventing water levels from rising, flooding into sewage treatment plants, drainage pumping stations, preventing the spread of sewage or liquid odours, and preparing for drainage.
