Benefits of Our Products:
-
Effective One-Way Sealing: The umbrella design allows controlled air outflow for pressure equalization while reliably sealing against backflow, preventing contamination.
-
Maintains Package Integrity: Prevents vacuum lock or bloating in containers, protects product freshness, and extends shelf life by allowing gases to escape.
-
Food-Safe & Durable: Certified LSR material offers excellent resistance to aging, temperature extremes, and maintains flexibility for millions of cycles.
-
Precision-Engineered Performance: Customizable crack pressure, flow rate, and dimensional tolerances ensure optimal performance for your specific packaging system.
Quality Assurance:
Our quality assurance for OEM Silicone Umbrella Check Valves is defined by rigorous, function-focused testing and certified manufacturing standards. Holding ISO 9001 and FDA-compliant material certifications, we ensure every valve meets food-contact safety regulations. Each production lot is subjected to stringent inspections, including precise crack pressure and airflow rate testing, 100% leak-testing under simulated pressure/vacuum cycles, and dimensional verification with precision gauges. This ensures consistent, reliable one-way performance and long-term durability in real-world applications.
