Quality Assurance:
Quality assurance for our LSR Umbrella Valves is defined by stringent functional and safety testing. We begin with certification of FDA/LFGB-compliant LSR materials. Each production batch undergoes 100% automated leak testing to verify seal integrity under specified back-pressure. Statistical sampling validates precise opening pressure and airflow rates using digital flow meters. Dimensional accuracy of critical sealing surfaces is confirmed with optical measurement systems. Our ISO 9001 certified process, with full batch traceability, ensures every valve performs as a reliable, food-safe barrier.
