- Duckbill check valves allow flow in only one direction through a pipe or tube while preventing any backflow in the opposite direction. When fluid pressure is applied from the upstream side, the duckbill flexes open to allow flow. But if pressure comes from the downstream side, the duckbill flaps seal shut to block reverse flow.

- What Are The Benefits?
By controlling and preventing backflow, check valves prevent discharges from wastewater treatment plants from contaminating clean water supplies. Check valves can also help prevent flooding, standing water, ensure water flows in the correct direction and prevent potentially harmful phenomena such as water hammers. In addition, check valves are wide...
There are also potential health and environmental impacts. In many urban environments, excess stormwater is drained into the existing sewerage system, where the network can become overwhelmed, resulting in the backflow and overflow of contaminated water.

Typically, the two halves form a beak-like appendage that allows a fluid to flow easily in one direction.
Duckbill check valves are essential components in fluid handling systems, designed to allow flow in one direction while preventing backflow. Their unique design features a flexible elastomer sleeve with a duckbill-shaped opening that opens under forward flow conditions and closes tightly to prevent reverse flow.
