China Valve Packing Co., Ltd.

Complementing our valves, we provide premium sealing gaskets and packing materials designed to resist chemical corrosion, thermal cycling, and mechanical stress. All products undergo rigorous testing by third-party institutions and are certified to globally recognized standards, including API 622, API 624, API 641, ISO 15848-1, and TA-LUFT, with verification from TüV Süd and TüV Rheinland.

Driven by a commitment to innovation and sealing excellence, we began early R&D into low-emission graphite packing solutions to meet the strict environmental requirements of markets such as the United States. Our long-standing partnerships with top universities and research institutions have enabled us to overcome complex technical challenges involving valve leakage, friction, and wear. These efforts culminated in our first TüV-witnessed API 622 certification and have since led to a comprehensive suite of international approvals, reinforcing the real-world performance and reliability of our valves.

What sets us apart is our scientific approach to valve engineering. While many focus solely on machining, we go further—studying the behavior of non-metallic materials under pressure and temperature, developing advanced sealing surface coatings, and analyzing long-term friction and wear. Our multidisciplinary team of experts in valve design, sealing systems, materials science, and automation collaborates to deliver smarter, more reliable valves. By bridging academic research with industrial application, we help our customers achieve greater operational safety, efficiency, and durability—earning their trust across a wide range of industries.
