The role of flexibleDuckbill Valve : Commonly known as the flexible rubber duckbill valve discharge valve, back-pressure flexible check valve, duckbill check valve, rubber check valve, rubber check valve, rubber slow closing check valve. This product is made of high quality elastic rubber material, built-in reinforced fiber material, under different conditions need to take a different structure and selection of different material formulations, according to a patented process elaborate, long life, easy installation. Factory subject to special hydraulic test bench testing, and to provide users with accurate test reports and performance curves. The valve does not have any active components, free of any maintenance. The valve can give straight pipe, flange pipe, concrete pipe, glass pipe support, the valve is widely used in coastal, beach, pier, reservoirs, municipal drainage, sewerage, can be described as environmentally friendly green valve that replaces shoot doors, gates , solve shoot the door easily sediment, silt, rocks, vegetation, marine life congestion.
