Product Introduction
Duckbill valve is a unique fluid control device, which is widely used in modern industrial, agricultural and municipal construction, with its efficient, reliable and economical advantages to handle a variety of fluids.
The design and functionality of the duckbill valve makes it a significant advantage when handling fluids, whether it is sewage treatment, stormwater drainage systems, or underground parking lot drainage systems, duckbill valves are effective in preventing the backflow of sewage or floodwater and protecting infrastructure from damage.
How it works
The working principle of the duckbill valve is based on its special design, when the liquid passes through the valve, the shape of the canap of the valve automatically adjusts the size of the opening according to the change in flow rate or pressure, ensuring that the fluid can be discharged smoothly. When the water flow stops, the duckbill valve closes tightly, preventing liquid or odor from backing up.
The valve does not require any moving components, is therefore maintenance-free, and prevents solid particles from jamming and ensures a tight shut-off.
Product Advantages
· Resilient rubber construction that requires no maintenance and prevents backfilling.
· It prevents flooding and sewage from backing up into street sewers and basements, preventing major losses.
· It is a quasi-water seal device, which can isolate the odor of outdoor inspection wells.
· It is not easy to freeze when opening and closing, and the loss of opening head is small.
· Long life, good sealing performance, anti-odor back, meet the requirements of water (air) sealing of indoor drainage ditches and outdoor drainage pipes.
· In the process of drainage, it can effectively prevent backflow and sediment formation.
· The diffusion performance is good, the jet speed is fast, the energy is large, and the discharge port has better diffusion than other standard round nozzles.
· It has the characteristics of cushioning, sound damping, maintenance-free and non-corrosion.
