Top 10 duckbill check valve Manufacturers in China

Introduction to Duckbill Check Valve

A duckbill check valve is a type of one - way valve that is designed to allow fluid to flow in only one direction. It gets its name from its shape, which resembles the bill of a duck. The valve is made of flexible materials such as rubber, and it operates based on the differential pressure across it. When the pressure on the inlet side is higher than the outlet side, the duckbill opens, allowing fluid to pass through. Once the pressure on the outlet side exceeds the inlet pressure, the duckbill closes, preventing backflow. Duckbill check valves are widely used in various industries, including wastewater treatment, drainage systems, and marine applications due to their simple design, low maintenance requirements, and reliable performance.
