Description:
Our Customized Plastic Bottle Cap One Way Check Silicone Cross-Slit Valves are designed to deliver precise, leak-proof dispensing performance for liquid packaging and closure systems. Manufactured from 100% FDA- and LFGB-compliant, food-grade liquid silicone rubber (LSR), these valves are produced through precision liquid injection molding (LIM) to ensure exceptional dimensional stability, durability, and hygiene. The unique cross-slit geometry allows for controlled one-way flow, preventing leakage, backflow, or contamination, making them ideal for beverage bottles, condiment dispensers, personal care, and healthcare packaging solutions. Engineered for reliability, flexibility, and safety, our valves withstand repeated cycles of compression without loss of function. We provide fully customizable OEM solutions, including slit size, opening pressure, cap integration, and color options—meeting both standard and specialized application needs.

Quality Assurance:
Quality assurance for OEM silicone cross-slit one-way valves emphasizes safety, precision, and consistency. All raw silicone materials are BPA-free, FDA- and LFGB-certified, verified by spectrometer analysis. During production, dimensional accuracy is controlled with Coordinate Measuring Machines (CMMs), optical microscopes, and 3D projectors. Shore A durometers and elasticity gauges ensure optimal hardness and rebound performance, while sealing and leak-proof tests confirm functional reliability under real-use conditions. Aging and thermal resistance are evaluated in high-temperature/low-temperature chambers to simulate extreme environments. Each batch is fully traceable and inspected in our ISO 9001 and IATF 16949 certified facility, ensuring compliance with the highest industry and safety standards.
