Understanding Duckbill Valves

What Are Duckbill Valves?

Duckbill valves are innovative one-way valves designed to allow fluid flow in a single direction while preventing backflow. Characterized by their unique duckbill shape, these valves open under pressure and close automatically when the pressure drops, ensuring effective backflow prevention.
