Overview
Our OEM food-safe silicone cross-slit dispensing valves are engineered for mess-free, precision ketchup dispensing in inverted squeeze bottles and condiment dispensers. Manufactured from 100% food-grade LSR or silicone and produced with micro-precision die cutting and LSR injection/compression molding, each valve delivers reliable one-way flow, fast reseal, and drip-free performance even with high-viscosity sauces. Fully customizable in diameter, slit geometry, hardness and color, these valves are optimized for consistent portion control, easy cleaning, and long service life in food-service and retail packaging applications.

Key Benefits
- Drip-Free, Mess-Free Dispensing: Cross-slit geometry provides secure one-way sealing that prevents leaking and stringing when inverted.
- Precision Portion Control: Tunable slit profile and material hardness allow reliable metered dispensing for thick condiments.
- Food-Safe & Durable: LFGB/FDA-approved LSR resists staining, odors, and food acids; maintains elasticity across hot/cold cycles.
- Easy to Clean & Maintain: Smooth, non-porous surfaces minimize residue buildup and are compatible with common cleaning protocols.
- OEM Flexibility: Custom diameters, slit counts, colors, and logo options—suitable for retail, foodservice, and private-label brands.
Quality Assurance
All valves are produced under an ISO 9001 quality system with full incoming material traceability. Each batch undergoes raw-material verification (LFGB/FDA/ROHS), dimensional inspection with 3D optical projectors and CMM where required, slit-geometry verification, and flow-rate calibration using industry-standard viscous fluid tests. Finished parts are tested for leak-proof performance under pressure differentials, long-term actuation durability (cycle testing), and accelerated thermal/chlorine/chemical exposure to ensure consistent function and hygienic integrity. Complete batch traceability and inspection reports accompany production lots.
