China Valve Packing Co., Ltd.

China Topper Valve Packing Seal Kits Co., Ltd. is a specialized manufacturer focused on high-performance industrial valves, sealing gaskets, and packing solutions for critical service applications in demanding industries. Our core valve portfolio—gate, globe, and ball valves—is engineered in full compliance with stringent API standards and integrates advanced low-leakage graphite packing to ensure reliable performance under extreme pressure and temperature conditions.

In addition to valves, we supply premium sealing gaskets and packing materials designed to withstand chemical corrosion, thermal cycling, and mechanical stress. All products undergo rigorous third-party testing and are certified to internationally recognized standards, including API 622, API 624, API 641, ISO 15848-1, and TA-LUFT, with verification by TÜV SÜD and TÜV Rheinland, ensuring proven emissions control and operational reliability.

Innovation and sealing excellence are at the core of our development strategy. We were among the early pioneers in low-emission graphite packing R&D, addressing the strict regulatory requirements of markets such as the United States. Through long-term collaboration with leading universities and research institutions, we have successfully tackled complex challenges related to valve leakage control, friction management, and wear resistance. These efforts culminated in our first TÜV-witnessed API 622 certification and have since expanded into a comprehensive portfolio of international approvals, validating our solutions under real operating conditions.

What truly differentiates China Topper is our scientific approach to valve engineering. Rather than focusing solely on machining precision, we delve into the behavior of non-metallic sealing materials under extreme service conditions, develop advanced sealing-surface coatings, and analyze long-term friction and wear mechanisms. Our multidisciplinary team—spanning valve design, sealing technology, materials science, and automation—works collaboratively to deliver smarter, safer, and longer-lasting valve solutions.

By effectively bridging academic research with industrial application, we help customers enhance operational safety, improve efficiency, and extend service life—earning long-term trust across a broad spectrum of industries worldwide.
