China Topper Valve Packing Seal Kits Co., Ltd. is a specialized manufacturer of high-performance industrial valves, sealing gaskets, and packing solutions tailored for critical and high-demand applications. Our comprehensive valve lineup—including gate, globe, and ball valves—is engineered to comply with strict API standards, integrating advanced low-emission graphite packing to ensure exceptional sealing performance under extreme pressures and temperatures.

In addition to valves, we manufacture premium gaskets and packing materials that are engineered to withstand chemical corrosion, thermal shock, and mechanical stress. All our products undergo independent third-party testing and are certified to globally recognized standards such as API 622, API 624, API 641, ISO 15848-1, and TA-LUFT, with verification by TÜV SÜD and TÜV Rheinland.

Our strength lies in a science-driven approach to sealing technology. From the early stages, we invested in R&D focused on low-leakage graphite packing solutions to meet stringent emissions standards in markets like the United States. Through deep collaboration with leading universities and research institutions, we've tackled complex challenges in leak prevention, friction control, and wear resistance—achievements that led to our first TÜV-witnessed API 622 certification and a broad portfolio of international approvals.

What differentiates us is our systematic and scientific understanding of valve reliability. While many manufacturers focus primarily on machining, we go further—analyzing the mechanical behavior of non-metallic materials, developing advanced sealing surface coatings, and studying the long-term effects of friction and wear. Our multidisciplinary team—spanning valve engineering, materials science, sealing technology, and automation—works in unison to deliver smarter, longer-lasting, and more efficient valve solutions.

By uniting research excellence with industrial expertise, China Topper empowers customers across a wide range of industries to enhance operational safety, efficiency, and service life, earning their continued trust and partnership.
