Custom Food Grade Non-Return Silicone One Way Duckbill Valves Suppliers

Overview:

Custom Food Grade Non-Return Silicone One Way Duckbill Valves offer simple, reliable backflow prevention. Manufactured from premium LSR via precision injection molding, their flexible slit design allows forward flow while sealing tight against reverse pressure. Our full OEM service provides custom sizing, cracking pressure, and flow characteristics tailored to your application.

Basic Information:

Benefits of Our Products:

• Robust, Zero-Maintenance Design: Integral duckbill structure eliminates internal seals or moving parts, ensuring long-term reliability and resistance to clogging in diverse media.

• Positive Anti-Backflow Protection: The self-sealing lips provide excellent shutoff against back pressure, effectively preventing contamination and maintaining system integrity.

• Superior Fluid Compatibility: Made from certified LSR, these valves resist degradation from a wide range of fluids, fats, and cleaning agents, ensuring long service life.

• Engineered Flow Control: We customize bill geometry, wall thickness, and material durometer to achieve your exact requirements for opening pressure, flow rate, and fluid viscosity.

Quality Assurance:

Our quality assurance for Duckbill Valves is enforced through rigorous functional testing and adherence to international standards. Operating under an ISO 9001-certified system and utilizing FDA-listed, USP Class VI-compliant LSR materials, we guarantee safety for food and fluid contact. Every production batch undergoes comprehensive validation, including functional tests for forward flow consistency, 100% individual seal integrity testing under specified back-pressure, precise dimensional verification, and material property checks. This ensures each valve delivers reliable, repeatable non-return performance.
