One-Way Liquid Silicone Rubber Duckbill Valve Supplier

- Nov 07, 2019-

Duckbill valves are unique, one-piece, elastomeric components that act as backflow prevention devices or one-way valves or check valves. They have elastomeric lips in the shape of a duckbill which prevents backflow and allows forward flow. The main advantage of duckbill valves over other types of one-way valves is that duckbill valves are self-contained i.e. the critical sealing function is an integral part of the one-piece elastomeric component as opposed to valves where a sealing element has to engage with a smooth seat surface to form a seal. Therefore duckbill valves are easily incorporated and assembled into a wide variety of devices without the hassle or problems associated with the surface finish quality of mating seats and/or complex assembly processes.


Other not less important features include:

  • 1. Position independent,

  • 2. Low opening pressure- immediate free flow,

  • 3. Non-tortuous flow path,

  • 4. High flow rate vs. package size,

  • 5. Virtually no internal volume and dead space,

  • 6. Particle compliant,

  • 7. Corrosion-resistant,

  • 8. Wear-resistant and

  • 9. last but not least very cost-effective.
