DESCRIPTION
Specification
Silicone cross slit valve is a type of one-way flow control valve made from liquid silicone rubber. It opens under pressure during squeezing and instantly reseals when pressure is released — ensuring drip-free, hygienic dispensing. This makes it perfect for applications that require clean, controlled flow and airtight sealing. These valves are commonly integrated into dispensing closures, flip caps, spouts, and flexible pouches across various industries.

Product Information
Our valves are used widely across the food, beverage, and personal care industries, including:
Sauce & Condiment Bottles — For ketchup, mustard, mayonnaise, salad dressings, and barbecue sauce.
Ensures clean cut-off, consistent dispensing, and drip-free flow.
Honey & Syrup Dispensers — Prevents leakage and crystallization, providing smooth and precise flow.
Flexible Pouches & Stand-Up Pouches — Perfect for baby food, fruit purees, sauces, and pet food spouts.
Inverted Bottles — Maintains perfect sealing under gravity pressure for "ready-to-dispense" bottles.
Flow Control Closures — For products requiring accurate flow rate and controlled dispensing experience.
Resealable & Recyclable Caps — Suitable for brands focusing on sustainability and consumer convenience.
We provide a wide selection of cross slit valve sizes to meet different flow requirements and product viscosities:
● 8mm Cross Slit Valve – for thin liquids or low-viscosity concentrates
● 9.8mm Cross Slit Valve – for beverage closures and water enhancers
● 10.5mm Cross Slit Valve – suitable for medium-viscosity sauces
● 12.85mm Cross Slit Valve – for condiments, honey, and syrups
● 13mm Cross Slit Valve – for squeezable bottles and dressings
● 16.5mm Cross Slit Valve – for thicker sauces or creams
● 18mm Cross Slit Valve – for high-viscosity dispensing products
● 21mm Cross Slit Valve – for heavy or large-volume product flow
Each size can be customized with different cross slit designs (X-slit, triple-slit, or custom patterns) to achieve the desired flow control and sealing performance.
| High Precision LSR Injection Molding | We produce all valves using advanced liquid silicone rubber injection molding to ensure consistent dimensions and superior elasticity. |
Automatic Slit Cutting & Punching | Fully automated post-molding processes guarantee uniform slit geometry and precise flow performance. |
Material Safety & Food Compliance (FDA, EU, LFGB) | All materials are food-grade certified, safe for direct food contact, and comply with major international standards. |
Performance for Viscous Products | Our valves maintain excellent sealing and flow control, even for thick products like ketchup, mayonnaise, or honey. |
Hygienic & Easy-to-Clean Design | Silicone's natural resistance to bacteria and its ability to withstand sterilization ensure a hygienic dispensing solution. |
Integration with Closures / Caps / Spouts | Our valves can be fitted into standard plastic closures or customized to your specific design, making them easy to adopt for packaging manufacturers. |
How to Use
For this kind of food grade no spill silicone slit valve, it's assembled together with the plastic valve seat, then fixed into the plastic flip top caps as a whole set.
