Overview
Our 10.5mm one-way silicone valves are purpose-built for controlled, drip-free dispensing of viscous condiments — ketchup, mustard, BBQ sauce and similar formulations — in flip-top and squeeze bottle caps. Manufactured from food-grade LSR (FDA & LFGB compliant) using precision injection molding and micro-slit finishing, each valve delivers reliable one-way flow, rapid shut-off, and long service life under repeated compression. Designed for easy snap-in or overmold integration with common cap systems, these valves are fully customizable for slit geometry, hardness, and opening pressure to match product viscosity and brand experience.

Key Benefits
- Drip-Free Dispensing: Cross-slit design and calibrated opening pressure prevent dripping and reduce product waste.
- Food-Safe & Clean: Molded from FDA/LFGB-approved LSR with hygienic surface finish suitable for direct food contact.
- Tailored Flow Control: Adjustable slit geometry and hardness to match viscosities from thin sauces to thick condiments.
- High Durability: Engineered for >100,000 compression cycles and resistant to temperature, oils, and acids common in foods.
- Plug-and-Play Integration: Compatible with standard flip-top and screw cap closures for quick assembly or overmolding.
Typical Performance Parameters (Guidance)
- Recommended Viscosity Range: ~5,000 – 150,000 cP (dependent on slit geometry).
- Target Opening Force: 0.5 – 3.0 N (tunable via slit profile and Shore A hardness).
- Life Cycle: Designed for 100k+ actuations under normal use; validation testing available per application.
Quality Assurance
- Material Control: Incoming LSR batches verified by COA and FTIR for FDA/LFGB compliance.
- Dimensional Inspection: First-article and sampling with CMM and optical comparators; in-line statistical sampling.
- Functional Testing: Flow-rate profiling, leak/pressure-hold tests, opening-force measurement, and drip trials with target sauces.
- Durability & Resistance: Compression fatigue, thermal cycling (−40°C to +230°C), and chemical resistance tests.
- Traceability & Cleanroom Packing: Batch coding, full inspection records, and cleanroom final packing on request.
Factory Capabilities
Our advanced production facility combines CNC toolmaking, Mirror-EDM and precision wire cutting for high-accuracy LSR tooling, automated LSR injection molding cells with dose-controlled metering, and micro-precision slit cutting (laser or micro-blade) to guarantee uniform slit geometry and repeatable flow characteristics; cleanroom assembly, automated leak testing, and inspection equipment (3D projectors, durometers, optical vision systems) ensure hygienic, traceable, high-volume output — all backed by ISO 9001 and IATF 16949 certifications and full OEM support from DFM to global delivery.
