China Valve Packing Co., Ltd.

China Topper Valve Packing Seal Kits Co., Ltd. is a specialized manufacturer of high-performance industrial valves, sealing gaskets, and packing solutions, engineered for critical applications in the world’s most demanding industries. Our product range includes precision-engineered gate, globe, and ball valves, designed in full compliance with stringent API standards. Each valve incorporates advanced low-leakage graphite packing to deliver superior reliability under extreme pressure and temperature conditions. Complementing our valves, we produce sealing gaskets and packing materials that provide outstanding resistance to chemical corrosion, thermal cycling, and mechanical stress. All products undergo rigorous 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 from TüV SüD and TüV Rheinland.

Innovation has been central to our growth. We pioneered early R&D in low-emission graphite packing systems to meet the strict environmental regulations of markets such as the United States. By collaborating closely with leading universities and research institutions, we have solved complex challenges related to valve leakage, friction, and wear. These efforts earned us our first TüV-witnessed API 622 certification and have since led to a complete portfolio of international approvals, reinforcing the proven performance and reliability of our valves in real-world operations.

What truly distinguishes us is our scientific approach to valve engineering. Rather than focusing solely on 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 mechanisms. Our multidisciplinary team—spanning valve design, sealing systems, materials science, and automation—works together to create smarter, more durable solutions. By bridging academic research with industrial application, we empower our customers to achieve higher operational safety, efficiency, and service life, earning trust across industries worldwide.
