Overview:
Our 13.5mm Snowflake silicone sealing valve is an engineered one-way dispensing solution designed for ketchup, sauces, condiments and compatible water/dispensing bottle closures. Manufactured from platinum-cured, food-grade LSR (liquid silicone rubber) via high-precision LSR injection molding, the snowflake slit geometry delivers consistent single-squeeze dispensing, excellent anti-drip performance and long service life. Produced in an ISO-certified facility with full OEM and one-stop services (tooling, prototyping, molding, printing & packing), these valves are optimized for reliable sealing, low opening force, and easy integration with flip-top, sports and pump caps.

Key Benefits
- Reliable Anti-Drip Performance: Snowflake slit geometry provides precise, single-squeeze dispensing with minimal residue.
- Food-Safe & Temperature Resistant: Platinum-cured LSR meets food contact standards and tolerates wide temperature ranges.
- Low Opening Force & Consistent Flow: Tunable hardness and slit design deliver easy usability for consumers.
- OEM Ready & Scalable: From rapid prototyping to high-volume automated production with low MOQ options and full customization (size, color, printing).
Quality Assurance & Test Equipment:
All valves are manufactured in an ISO 9001-certified facility and pass a multi-stage inspection regime that begins with incoming raw-material verification and continues through in-process monitoring to final QA. Critical dimensions are measured with a Coordinate Measuring Machine (CMM), material hardness is checked with Shore A durometers, and polymer strength is assessed using tensile/elongation testers. Seal performance is validated with dedicated leak and seal-integrity testers (including inverted leak tests run for 24–168 hours as required), while 3D optical projectors and automated vision systems handle visual and geometric inspections. Thermal-cycling chambers verify temperature stability, and third-party laboratory testing for FDA/LFGB compliance is available upon request.
Typical Applications:
- Ketchup, mustard and condiment squeeze bottles
- Sports bottle caps and flip-top closures (water & electrolyte drinks)
- Travel and toiletry dispensers (shampoos, lotions)
- Foodservice and commercial dispensing closures
