Description:
Our Customized Leak-proof Silicone Valve is specifically designed for hydration bottles, delivering consistent one-way liquid flow with zero leakage. Crafted from 100% FDA- and LFGB-compliant, food-grade silicone, these valves are produced through precision liquid silicone rubber (LSR) injection molding, ensuring exceptional dimensional accuracy, elasticity, and repeatability. The cross-slit design allows smooth, controlled dispensing while preventing backflow and contamination—ideal for sports bottles, outdoor hydration systems, and portable water dispensers. With excellent resistance to temperature extremes (–40 °F to 450 °F), durability under repeated compression cycles, and full dishwasher safety, this valve is engineered to withstand demanding daily use. As your OEM manufacturing partner, we provide end-to-end customization—covering dimensions, hardness, slit geometry, and branding—delivering high-performance silicone solutions tailored to your exact requirements.

Quality Assurance:
Our quality assurance program for silicone valves prioritizes safety, reliability, and compliance with international standards. All raw silicone materials are verified to be FDA, LFGB, and RoHS compliant before production. Each valve is manufactured in our ISO 9001- and IATF 16949-certified facility using precision LSR injection molding under strictly controlled conditions. Testing protocols include flow rate calibration, backflow resistance, cycle fatigue testing, Shore A hardness verification, tensile strength measurement, and high-temperature/cold resistance validation. Additional dimensional and visual inspections ensure consistent 16mm geometry and flawless cross-slit function. Final QC is performed with full traceability in a cleanroom-controlled environment to guarantee performance in demanding hydration and dispensing applications.
