Duckbill valve classification: socket-style duckbill valve, mosaic duckbill valve, duckbill valve flange, install the plate duckbill valve, duckbill valve, built-duckbill valve.
Duckbill valve installation: Flange duckbill valve installed in the drain outlet end with a flange. Duckbill valve installed in the socket-type drain export, mosaic duckbill valve installed in the middle of the city sewer pipes. Installation plate Duckbill valve installed in the outlet end of the buildings. Built-duckbill valve installed in the city sewer and water system ends. Mortar or cement pipeline duckbill valve installed in the mortar or cement pipe end.
Duckbill valve installation method and size: the rubber flange, made of one body and beak, and the metal flange with a gasket, you can connect with the natural metal flange, directly installed in the tank, pipes and cofferdam on. Installation connection, flange and flange dimensions correspond to the flange with the flange, as the case should be added between the waterproof glue, sealed to ensure absolute connection after fastening, but also be careful not to break something duckbill valve flange lips. Duckbill valve Material: Neoprene, Haipu Long, nitrile rubber and ethylene-propylene rubber. Flexible rubber duckbill valves, also known as check valves, slow closing check valve rubber, rubber sewage check valve. XH81, XH81A, XH41, XH41A duckbill-type valve (Spain called "flexible duckbill check valve"; the United States known as the "duckbill valve rubber flat mouth") is a valve company in Spain ROSS, American Red Valve Company production based on the summary, exemplary, revolutionary re-design. We are committed to continuous improvement (duckbill check valve flexible) rubber discharge check valve function, improve performance, so that the valve of the strength, toughness, sealing greatly improved, the valve does not have any active components, the avoidance of maintenance. The valve can give straight pipe, flange pipe, concrete pipe, glass pipe support, the valve is widely used in coastal, beach, docks, reservoirs, municipal drainage, sewage, can be described as environmentally friendly green valve, the valve replacement door check valves, door easily solve the sediment, silt, rocks, vegetation, marine life blocking problems.
