China Valve Packing Co., Ltd.
China Topper Valve Packing Seal Kits Co., Ltd. is a leading manufacturer specializing in high-performance industrial valves, sealing gaskets, and packing solutions for critical applications across demanding industries. Our portfolio—including gate, globe, and ball valves—is engineered to meet rigorous API standards, featuring advanced low-leakage graphite packing for reliable performance under extreme pressure and temperature conditions. Complementing our valves, we supply premium sealing gaskets and packing materials designed to withstand chemical corrosion, thermal cycling, and mechanical stress. All products are third-party tested and certified to global standards, including API 622, API 624, API 641, ISO 15848-1, and TA-LUFT, with verification from TÜV SÜD and TÜV Rheinland. Committed to innovation and sealing excellence, we pioneered research and development in low-emission graphite packing solutions to meet the stringent demands of markets such as the United States. Our long-term partnerships with top universities and research institutions have allowed us to tackle complex challenges related to valve leakage, friction, and wear. These efforts earned our first TÜV-witnessed API 622 certification and have since resulted in a comprehensive suite of international approvals, demonstrating the performance and reliability of our products in real-world conditions. What sets China Topper apart is our scientific approach to valve engineering. Beyond precision machining, we study the behavior of non-metallic materials under pressure and temperature, develop advanced coatings for sealing surfaces, and analyze long-term friction and wear. Our multidisciplinary team—experts in valve design, sealing systems, materials science, and automation—integrates academic research with industrial application to deliver smarter, safer, and longer-lasting valves. This commitment helps our customers maximize operational safety, efficiency, and service life, earning their trust across diverse industries.
