The duckbill valve is made of elastic neoprene and man-made fibers that have been specially processed. The shape resembles a duck's bill, so it is called a duckbill valve. When there is no internal pressure, the duckbill outlet closes under its own elastic action;As the internal pressure gradually increases, the duckbill outlet gradually increases to keep the liquid drained at a high flow rate.
The duckbill valve, also known as the rubber slow-closing check valve, is widely used in major water plants, municipal, water conservancy and other places.
The rubber duckbill valve opens and closes according to the water pressure difference. Although the duckbill valve has no moving parts, it can still be simply opened. Safe and reliable, no noise, no power supply, no manual operation, no follow-up maintenance.
The rubber duckbill valve is an all-rubber joint, which inherits the high elasticity, plasticity, and heat resistance of rubber. No rust, anti-solidification, anti-aging, no maintenance costs;The rubber duckbill valve ensures that the valve has an automatic cleaning function. No sediment and silt deposits;The flexible rubber formula has good anti-backflow and backflow performance, and the unique shape and structure make the duckbill valve have good sealingIt is easy to install, and there is basically no need for installation and civil construction costs. It can be installed at the end of the water outlet such as cement pipe, corrugated pipe, steel pipe, glass pipe, etc., and the installation form is diverse, which can be determined according to the actual working conditions of the userIt has good frost resistance, and the valve body has good flexibility and elastic deformation.
