China Topper Valve Packing Seal Kits Co., Ltd. (https://www.valvepackingsealkits.com/
) is a specialized manufacturer of high-performance industrial valves, sealing gaskets, and packing solutions designed for the most demanding applications. Our valve portfolio—including gate, globe, and ball valves—is engineered to meet rigorous API standards, featuring advanced low-leakage graphite packing for exceptional performance under extreme pressures and temperatures.
In addition to valves, we provide premium sealing gaskets and packing materials that withstand chemical corrosion, thermal cycling, and mechanical stress. All products undergo third-party testing and carry internationally recognized certifications such as API 622, API 624, API 641, ISO 15848-1, and TA-LUFT, verified by TüV SÜD and TüV Rheinland.
Innovation drives our approach. From the early stages, we focused on developing low-emission graphite packing solutions to meet stringent global market requirements, including those in the United States. Collaborations with leading universities and research institutions have enabled us to address complex challenges related to valve leakage, friction, and wear, culminating in our first TüV-witnessed API 622 certification and a full suite of international approvals that underscore the reliability of our solutions.
What truly sets us apart is our scientific approach to valve engineering. Beyond precision machining, we study non-metallic material behavior under extreme con
