Thanks to its self-sealing cross-slit structure, the valve minimizes air exposure after each use. This prevents oxidation, contamination, and flavor loss—ideal for sensitive products like liquid supplements, cosmetic serums, and concentrated sauces. Whether used as an X-slit valve or slit valve for air-sensitive liquids, it preserves quality while reducing waste. To support your R&D or packaging project, we offer:
1. Technical 2D drawings upon request
2. Free samples (shipping at buyer's expense)
3. Support for flow rate testing based on your product's viscosity and container design

FAQ
| Q: What is a cross slit valve? A: A cross slit valve is a flexible valve with an X-shaped cut (also called an X-slit valve) that opens under pressure and seals automatically when not in use. It ensures controlled dispensing and prevents leakage or contamination. |
Q: What's the difference between a silicone slit valve and a cross slit valve? A: A slit valve typically refers to any valve with a narrow opening or cut, while a cross slit valve specifically features a cross- or X-shaped cut that enables more consistent, drip-free flow—ideal for liquids like sauces, lotions, and serums. |
Q: Why choose an LSR cross slit valve for squeeze bottles? A: LSR (Liquid Silicone Rubber) offers excellent flexibility, elasticity, and sealing performance. An LSR cross slit valve is ideal for squeeze bottles and dispensing closures due to its leak-proof, self-sealing, and customizable design. |
Q: Can I customize the flow rate of the silicone cross slit valve? A: Yes. The silicone rubber slit valve can be manufactured with various slit sizes (e.g., 1.5×1.5mm, 2×2mm, 3×3mm) to control flow rate and activation pressure depending on your product and packaging |
Q: Is the 8mm cross slit valve food-safe? A: Absolutely. Our 8mm silicone cross slit valves are molded from food-grade LSR and compliant with FDA and EU regulations, making them suitable for condiments, baby care, and cosmetics. |
