The rubber duckbill valve is a versatile check valve that can be easily incorporated into a variety of devices. These valves are also easy to install and assemble, requiring no complex assembly processes or surface finish requirements on the mating seats. These features make these valves an ideal choice for many different applications.
Flexible check valve
A flexible duckbill valve is a versatile device that can be used for a variety of fluid control applications. Its design is simple and allows it to handle fluids with little or no change in pressure. This rubber duckbill check valve type of valve is also resistant to corrosion.
The rubber duckbill valve is an economical solution for reducing headloss in water systems. Its sloping bottom prevents water from entrapping and ensures zero backflow. Its smallest opening pressure of only one to two inches allows for maximum drainage, eliminating upstream flooding.
Improves hydraulic performance
A rubber duckbill valve is a passive check valve that offers several advantages over mechanical check valves. They are non-corrosive, do not rust, and do not bind or seize when exposed to corrosive materials. These properties significantly enhance the reliability and longevity of a hydraulic system. Moreover, they are free from mechanical wear, which can negatively impact check valves made of other materials.
A rubber duckbill valve is a low-cost way to prevent backflow. They can be installed in vertical or horizontal applications, and are low-maintenance and low-pressure valves. The seal is excellent, providing maximum flow with minimal pressure drop across the valve. They are also effective in preventing blockage due to large objects.
