Overview
Our LSR Molding Leakage-Proof No-Spill Food Grade 10.5mm Silicone Check Valves are engineered for precise and hygienic liquid control in honey bottles, syrup dispensers, and condiment packaging. Designed to enable smooth, one-way dispensing without drips or leaks, these valves are made from FDA- and LFGB-compliant food-grade silicone, ensuring maximum safety, elasticity, and long-term durability.
Manufactured via liquid silicone rubber (LSR) injection molding with micro slit-die precision cutting, each valve provides consistent flow control and a clean sealing response—ideal for thick and viscous liquids such as honey or sauces.

Quality Assurance
Each silicone valve undergoes a strict quality control process to ensure functional reliability and compliance:
- Raw Material Validation: Tested for FDA, LFGB, and RoHS compliance before molding.
- Dimensional Precision Checks: Automated 3D optical inspection for slit geometry and thickness accuracy.
- Performance & Flow Testing: Verifies no-leak performance and consistent one-way dispensing for viscous liquids.
- Durability Testing: Assessed under repeated compression and temperature cycling (-40°C to +230°C).
All inspections are performed within our ISO 9001 and IATF 16949 certified cleanroom, guaranteeing consistent food-grade safety and performance.
