China Valve Packing Co., Ltd.

China Topper Valve Packing Seal Kits Co., Ltd. (https://www.valvepackingsealkits.com/) is a specialized manufacturer committed to delivering high-performance industrial valves, sealing gaskets, and packing solutions designed for critical applications across demanding industries. Our product portfolio includes gate, globe, and ball valves engineered to meet rigorous API standards, featuring advanced low-leakage graphite packing that ensures exceptional performance under extreme pressure and temperature conditions.

In addition to valves, we provide premium sealing gaskets and packing materials engineered to withstand chemical corrosion, thermal cycling, and mechanical stress. All our products undergo strict third-party testing and carry certifications from globally recognized standards such as API 622, API 624, API 641, ISO 15848-1, and TA-LUFT, verified by TüV SüD and TüV Rheinland.

Our innovation-driven approach began with early R&D efforts focusing on low-emission graphite packing solutions to meet stringent market requirements, especially 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. These efforts culminated in our first TüV-witnessed API 622 certification and have since earned us a comprehensive suite of international approvals, underscoring the reliability and performance of our valves in real-world conditions.

What distinguishes us is our scientific and multidisciplinary approach to valve engineering. Beyond machining, we investigate the behavior of non-metallic materials under pressure and temperature, develop advanced coatings for sealing surfaces, and analyze long-term friction and wear dynamics. Our team of experts in valve design, sealing systems, materials science, and automation work collaboratively to create smarter, more reliable valves. By bridging academic research with industrial application, we enable our customers to achieve enhanced operational safety, efficiency, and durability, earning their trust across diverse industries.
