9.7mm Silicone X-slit Valve | High Precision Liquid Control One-Way Valve

9.7mm silicone X-slit valve（or cross slit valve）is a precision one-way flow control valve designed for dispensing caps and closures. Made from high-quality food-grade silicone, the valve features a flexible X-slit cut design that opens when the bottle is squeezed, allowing liquid to dispense smoothly while preventing leaks and backflow when pressure is released.

This no-drip silicone valve ensures clean and controlled dispensing, improving the user experience and reducing product waste. With excellent elasticity and durability, the valve quickly returns to its original shape after repeated use, maintaining consistent sealing and flow performance.

The 9.7mm X-slit valve is widely used in condiment squeeze bottles, personal care packaging, medical dispensers, and flip-top caps, making it an ideal solution for reliable liquid dispensing applications.

Product Information

Advantages of 9.7mm Silicone X-slit Valve

Smooth Dispensing for High Viscosity – The X-slit cut design allows for easier opening compared to other slit type valves, making it ideal for thicker liquids like sauces, honey, or gels.

Precision Anti-Drip Performance – The X-slit architecture ensures a clean "cut-off" of the liquid, preventing messy drips and buildup around the cap.

Superior Air-Backflow Prevention – Automatically seals tight to prevent air from entering the container, preserving the freshness of the product inside.

Food-Grade & BPA Free – Manufactured from high-quality liquid silicone compliant with FDA, LFGB, and REACH standards.

Excellent Fatigue Resistance – Maintains its structural memory and sealing integrity even after thousands of dispensing cycles.

Applications of 9.7mm  Silicone X-slit Valve

The 9.7mm silicone X-slit valve is engineered for medium-to-high viscosity liquids, where precise control and clean dispensing are critical.

Typical applications include:

Condiment Squeeze Bottles – For ketchup, mayonnaise, mustard, and honey.

Personal Care & Cosmetics – For shampoos, conditioners, body lotions, and sunscreens.

Medical & Healthcare – For precise dosage of gels or thick liquid medications.

Household Cleaning – For concentrated detergents, dish soaps, and gel cleaners.

Industrial Fluids – For lubricants or adhesives requiring controlled application.

FAQ

1. What is a silicone X-slit valve? 

A silicone X-slit valve (or cross slit valve) is a one-way dispensing valve. It features two intersecting slits that open under pressure and snap shut immediately when pressure is removed. It is the industry standard for squeeze-to-dispense packaging.

2. What is the difference between a silicone X-slit valve and a star-shape valve?

Silicone X-slit valves typically open more easily, making them better suited for medium-to-high viscosity liquids (like ketchup or gel). Star-shape valves have a higher opening pressure and are often preferred for low-viscosity liquids (like water or thin juices) to prevent accidental leaks.

3. Does this silicone X-slit valve prevent the "glugging" effect? 

Yes. By controlling the flow and allowing air to return in a regulated manner (depending on the container design), it helps provide a smooth, continuous stream without splashing.

4. Is the 9.7mm size customizable? 

While 9.7mm is a common outer diameter, YEJIA can customize the flange thickness, hardness (Shore A), and slit geometry to perfectly fit your specific cap design.

5. Can this silicone x-slit valve be used for hot-fill products? 

Yes. Our silicone valves are temperature resistant up to 230°C, making them suitable for hot-fill processes and sterilization.

6. How does YEJIA ensure the quality and consistency of silicone X- slit valves?
YEJIA implements strict quality control at every production stage, including material inspection, precision molding, coating application, and final performance testing to ensure consistent flow, anti-drip functionality, and durability.

7. What is the MOQ for custom silicone valves?

The minimum order quantity (MOQ) for custom silicone valves depends on the valve size, mold design, and production process. YEJIA provides prototype testing samples before mass production to ensure proper performance and compatibility with your packaging system.
