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 designed for the most demanding applications. Our product range—spanning gate, globe, and ball valves—is engineered to meet strict API standards and enhanced with advanced low-leakage graphite packing, ensuring superior performance under extreme pressure and temperature. To complement our valves, we supply premium sealing gaskets and packing materials with exceptional resistance to chemical corrosion, thermal cycling, and mechanical stress. Every product undergoes rigorous third-party testing and carries internationally recognized certifications, including API 622, API 624, API 641, ISO 15848-1, and TA-LUFT, verified by TÜV Süd and TÜV Rheinland.

From the outset, we have prioritized innovation in low-emission sealing technologies to meet the stringent requirements of global markets such as the United States. Through long-term collaborations with leading universities and research institutions, we have tackled critical challenges in valve leakage, friction, and wear. These efforts led to our first TÜV-witnessed API 622 certification and, over time, a complete suite of international approvals—further validating the reliability and real-world performance of our solutions.

What truly sets us apart is our scientific approach to valve engineering. Beyond precision machining, we explore the deeper material science—studying the behavior of non-metallic components under pressure and temperature, developing advanced coatings for sealing surfaces, and analyzing long-term friction and wear. Our multidisciplinary team, with expertise in valve design, sealing systems, materials engineering, and automation, integrates academic research with industrial application to deliver smarter, longer-lasting, and safer valves. By combining innovation with proven reliability, we help customers achieve higher efficiency, operational safety, and extended service life—earning trust across industries worldwide.
