Structural design of the clamp type duckbill valve

1.The Valve can employ materials such as neoprene, Hypalon, nitrile rubber (NBR), ethylene propylene diene monomer rubber (EPDM), fluororubber, and natural rubber.

2.It is equipped with a supporting ring made of galvanized carbon steel or stainless steel.

The Xinhua Feng Pipeline Equipment RH41-F series straight-nozzle Flanged Duckbill Valve is suitable for installation with pipe flanges or on walls. It features an all-rubber Flange that is integrally manufactured with the valve, ensuring excellent sealing performance, effective check functionality, quiet operation, and robust durability. The valve's opening and closing are controlled solely by the pipeline pressure and backpressure, without requiring any external force, thereby significantly reducing operational costs. Since the Valve Body of the Henan Runxing Pipeline Equipment RH41-F series contains no metal components, it avoids issues related to metal component failure or clogging, eliminating the need for maintenance hassles.

The Xinhua Feng Pipeline Equipment RH41-F series can easily handle corrosive and viscous media, such as sewage, sludge, and slurry. Even solid media can pass through without obstruction. When the valve closes, the flexible nozzle tightly wraps around any trapped solid impurities, achieving a perfect seal with no leakage.

The RH41-F series offers flexible installation options, allowing for vertical or inclined mounting based on specific working conditions. The flanges and bolt holes are processed according to user requirements.
