Description:
Our Customized Silicone One Way Cross Slit Valves are precision-engineered to provide accurate and leak-proof dispensing in liquid and air control systems. Made from 100% FDA-approved, food-grade liquid silicone rubber (LSR), these valves are produced using high-precision LSR injection molding and compression molding technologies to achieve exceptional consistency, elasticity, and sealing performance. The cross-slit design ensures controlled, one-way flow and prevents leakage or backflow, making them ideal for use in personal care, cosmetics, food packaging, medical devices, and household dispensing applications.
Engineered for high durability and superior chemical resistance, these silicone valves guarantee hygienic operation and long service life even under demanding conditions. Each valve is designed for easy integration into closures, pump systems, and dispensing components, ensuring smooth and reliable performance across diverse OEM applications.

Quality Assurance:
Our silicone cross slit valves undergo rigorous inspection and validation to ensure optimal quality and performance. Raw silicone materials are verified with spectrometers, durometers, and tensile testers to confirm FDA and LFGB compliance. During production, CMMs, optical projectors, and 3D microscopes are used to maintain precise slit geometry and sealing accuracy. Each batch is tested for air-tightness, flow rate uniformity, and fatigue life cycle under simulated working conditions. Final inspection is conducted in an ISO-certified cleanroom, ensuring each valve meets international hygiene and dimensional standards.
