Overview
Our OEM 7.2mm Silicone Umbrella Check Valves are engineered for reliable one-way fluid and air control across a wide range of applications — including beverage dispensers, hydration systems, medical disposables, cosmetic pumps, and small pneumatic assemblies. Manufactured from premium food-grade or medical-grade liquid silicone rubber (LSR) using precision LSR injection molding and CNC-polished tooling, the umbrella geometry provides fast opening, positive sealing, and exceptional particulate tolerance. Valves are fully customizable for opening force, port fitment, and hardness to match your system’s flow, pressure, and compatibility requirements.

Key Benefits
- Positive One-Way Flow Control — umbrella design opens quickly under applied pressure and reseals reliably to prevent backflow and leakage.
- Tunable Performance — valve geometry and Shore A hardness are optimized for your target opening pressure and media viscosity.
- High Durability & Cleanability — LSR chemistry resists acids, bases, surfactants, and repeated compression cycles while meeting food/medical safety requirements.
- Easy Integration — molded retention features and standard bore dimensions simplify assembly into caps, housings, or subassemblies.
Quality Assurance
We maintain rigorous QA across material, process, and performance: incoming LSR batches are verified for FDA/LFGB compliance; dimensional accuracy is confirmed via CMM and optical projectors; functional evaluation includes leak-rate testing under differential pressures, opening-force calibration, actuation fatigue testing (>100k cycles), and thermal/chemical resistance trials. Full lot traceability, batch documentation, and cleanroom final inspection ensure consistent, ready-to-ship OEM quality.
Factory Capabilities
Our production combines precision CNC moldmaking, mirror EDM, and automated LSR injection molding with cleanroom assembly and automated inspection. We support rapid prototyping to full-scale manufacture, with in-line testing equipment (leak testers, 3D projectors, durometers, and automated cycle testers) to guarantee repeatable performance and fast turnaround.
