Company Profile - China Valve Packing Co., Ltd.

China Topper Valve Packing Seal Kits Co., Ltd. focuses on manufacturing premium industrial valves, sealing gaskets and packing solutions for harsh industrial applications. Our gate, globe and ball valves adhere to strict API standards. Equipped with high-efficiency low-leakage graphite packing, they operate reliably in extreme pressure and temperature environments.
Our sealing accessories feature excellent resistance against chemical corrosion, thermal cycling and mechanical stress. Every product undergoes independent third-party testing and holds internationally recognized certifications such as API 622, API 624, API 641, ISO 15848-1 and TA-LUFT, certified by TÜV SüD and TÜV Rheinland.
We keep innovating sealing technologies and have dedicated ourselves to developing low-emission graphite packing to meet global market requirements. In partnership with top academic and research bodies, we have solved key technical problems of valve leakage, friction and wear. Having obtained TÜV-attested API 622 certification and a full range of international approvals, our products are proven highly reliable in field operation.
Different from peers that focus merely on machining, we adopt a scientific approach to valve engineering. We explore material characteristics, develop advanced coatings and study friction and abrasion performance. Our cross-disciplinary team combines cutting-edge research with practical production, delivering valves with superior safety, efficiency and service life. This has made us a trusted partner for clients across multiple industries.
