2026 Top 10 duckbill check valve Suppliers in China

Introduction to Duckbill Check Valve

A duckbill check valve is a type of one - way valve that allows fluid to flow in one direction and prevents backflow. It gets its name from its shape, which resembles a duck's bill. The valve operates based on differential pressure. When the upstream pressure is higher than the downstream pressure, the duckbill valve opens, allowing fluid to pass through. Once the upstream pressure drops or the downstream pressure rises, the valve closes to prevent reverse flow. This simple yet effective design makes duckbill check valves widely used in various industries such as wastewater treatment, stormwater management, and marine applications.
