Overview
Our Customized NSF-Approved Food Grade Silicone Ketchup Dispensing Valves with Cross-Slit Cut are precision-engineered for consistent, mess-free, and leak-proof dispensing of condiments such as ketchup, sauces, and dressings. Made from 100% food-grade, BPA-free liquid silicone rubber (LSR) compliant with NSF, FDA, and LFGB standards, these valves ensure superior hygiene, elasticity, and durability. The optimized cross-slit design enables smooth one-way dispensing while preventing leakage and backflow, making them ideal for fast-food packaging, condiment bottles, and foodservice applications. Supported by advanced LSR injection molding and micro-slit die-cutting processes, our valves deliver exceptional performance, consistency, and longevity in high-volume use.

Quality Assurance
At YJC Polymer, we follow strict quality management protocols under ISO 9001 and IATF 16949 certification frameworks. Every batch of silicone valves undergoes a multi-step inspection and testing process to guarantee food safety, functional reliability, and dimensional consistency.
- Raw Material Validation: All LSR materials are NSF, FDA, and LFGB certified, verified via third-party testing.
- Dimensional Accuracy: Each valve is measured using 3D optical inspection and micro-slitting geometry checks.
- Leakage & Flow Testing: Real-world simulation tests ensure mess-free, one-way dispensing under varying pressure conditions.
- Thermal & Chemical Resistance Testing: Validated to perform under temperature ranges from -40°C to +230°C and contact with acidic or oily condiments.
- Durability Testing: High-cycle compression tests simulate repeated use to confirm consistent elasticity and long-term reliability.
All inspection data is traceable, ensuring compliance with global food-contact and environmental regulations such as RoHS and REACH.
