China Topper Valve Packing Seal Kits Co., Ltd. is a specialized manufacturer of high-performance industrial valves, sealing gaskets, and packing solutions designed for critical applications in demanding industries. Our product range includes gate, globe, and ball valves, all engineered to meet rigorous API standards. These valves incorporate advanced low-leakage graphite packing, providing exceptional performance under extreme pressure and temperature conditions. Alongside our valves, we offer premium sealing gaskets and packing materials that excel in resisting chemical corrosion, thermal cycling, and mechanical stress.
All of our products undergo third-party testing and are certified under globally recognized standards, including API 622, API 624, API 641, ISO 15848-1, and TA-LUFT, with verification by TüV SüD and TüV Rheinland.
From the start, we have committed to innovation in sealing technology, beginning R&D into low-emission graphite packing to meet the stringent environmental standards of markets such as the United States. Our close collaborations with leading universities and research institutions have enabled us to solve complex challenges related to valve leakage, friction, and wear. This effort led to our first TüV-witnessed API 622 certification, and we continue to build on these advancements with a comprehensive suite of international approvals.
What sets us apart is our scientific approach to valve engineering. While many focus on machining, we dive deeper into the behavior of non-metallic materials under pressure and temperature, developing advanced coatings for sealing surfaces and studying long-term friction and wear. Our multidisciplinary team combines expertise in valve design, sealing systems, materials science, and automation to deliver smarter, more reliable valves. By integrating academic research with industrial application, we help our customers achieve higher operational safety, efficiency, and service life, earning their trust across a wide array of industries.
