Description
Our innovatively designed flower-shaped silicone duckbill check valves are precision-engineered using platinum-cured liquid silicone rubber (LSR) through advanced injection molding processes, combining exceptional leak-proof performance with aesthetic appeal. These valves feature a unique petal-inspired duckbill structure that ensures smooth, low-resistance flow in one direction while providing reliable sealing against backflow. Manufactured from 100% FDA-compliant, food-grade and medical-grade LSR, they withstand temperatures from -60°F to 400°F and are resistant to chemicals, oils, and sterilization methods (autoclave, EtO, gamma). Exceeding FDA 21 CFR, USP Class VI, and LFGB standards, these valves are ideal for applications requiring both functionality and visual elegance. As your dedicated manufacturing partner, we offer comprehensive OEM solutions—including custom sizes (10-50mm), flow rates, colors (Pantone-matched), and durometer hardness (Shore A 30-70)—backed by high-volume production capabilities. Perfect for premium consumer products, medical devices, and food packaging where design matters as much as performance.

Quality Assurance
Our quality assurance process begins with rigorous raw material testing using FTIR spectroscopy to verify material purity and GC-MS analysis to ensure absence of harmful substances. During production, we employ vision inspection systems to maintain precise dimensional tolerances (±0.05mm) and functional testing to verify cracking pressure (0.1–3 psi) and flow rates. Each valve undergoes 100% leak testing using pressure decay methods (ASTM F2096) and automated optical inspection for surface defects. Our ISO Class 7 cleanroom manufacturing environment ensures contamination-free production, with full batch traceability and compliance with ISO 9001 and ISO 13485 quality standards.
