We're proud to announce that ZOY has officially been granted a U.S. invention patent for our newly developed PSA oxygen system technology- Integrated Intake and Exhaust Valve and PSA Gas Circuit System (Patent No.US 12331840 B2)
This patent marks a major milestone in our journey of innovation and reflects ZOY's growing influence in the global oxygen generation industry.


Traditional oxygen systems often face issues like too many valve components, complicated pipe work, and time-consuming assembly. Our patented design solves these problems by.
Simplifying the structure: Multiple valves are integrated into a single valve block, making the lay out cleaner and easier to manage.
Improving efficiency: Fewer pipe connections mean faster installation and fewer potentialfailure points.
Boosting reliability: The system offers safer and more stable control of gas flow.
This technical breakthrough enhances ZOY's core strength in PSA oxygen system design. Moreimportantly, it supports the industry's shift toward smarter, safer, and more compact oxygensolutions.
With over 40 patents granted in China and abroad, ZOY continues to focus on R&D as a long-termstrategy. We are committed to delivering high-performance, low-maintenance oxygen generation systems for hospitals, clinics, and industrial users around the world.
Receiving this U.S. patent is more than a technical win - it's international recognition of ZOY'scapabilities. lt strengthens our reputation in the global market and shows the world what Chinese engineering can achieve.
