1. • Preventing backflow

     • Duckbill check valves consistently provide the tightest seal for preventing backflow. The flexible elastomer material can compress tightly around trapped solids if necessary. Its ability to resist ocean waves, freezing temperatures and scorching heat makes the valve one of the most specified valves on the planet.

   What is a duckbill valve?

   • Duckbill Valves are unique, one-piece, elastomeric components that act as backflow prevention devices. Also known as one-way valves or check valves. They have elastomeric edges, or lips, shaped in a way that resembles a duck’s bill (hence their name).

   How does a duckbill check valve work?

   • This process occurs seamlessly without external intervention, making duckbill check valves inherently passive and low-maintenance components. As the fluid flow subsides or attempts to reverse, the elasticity of the valve material ensures that the slit reverts to its closed position, effectively sealing off the passage.
