Magpie Valve Packing Gasket Co., Ltd

Magpie Valve is a leading manufacturer of industrial valves, packing, gaskets, and seal kits, driven by research and innovation. We are committed to advancing valve technology through material science, precision engineering, and rigorous third-party validation. Our mission is to redefine the role of valves in modern industry by focusing on the core factors that ensure reliability—most importantly, sealing performance.

While large-scale machining is no longer the main challenge in China’s valve industry, the true bottlenecks lie in areas often overlooked: the mechanical behavior of non-metallic materials, advanced coatings for sealing components, and the friction and wear mechanisms that dictate valve longevity. At Magpie, these are the fields where we invest our expertise and resources to deliver high-performance solutions.

Our multidisciplinary team includes nuclear-grade sealing engineers, valve experts, material scientists, and electromechanical specialists who combine academic insight with real-world application. In collaboration with institutions such as Lanzhou University of Technology’s National Key Friction Laboratory, Ningbo Institute of Materials, East China University of Science and Technology, and the Shanghai Institute of Ceramics, we have conducted extensive research into low-leakage graphite sealing technologies and developed systematic solutions to address the root causes of sealing failure.

With authoritative third-party testing and internationally recognized certifications—including API 622, API 624, API 641, ISO 15848-1, TA-LUFT, and ISO 15848-1 CC3—Magpie Valve ensures reliability at the highest standards. To date, we have tested nearly 500 valve products, including gate, globe, and ball valves, under extreme conditions ranging from 400°C to -196°C and up to Class 2500 LB pressure. These efforts not only guarantee compliance with global benchmarks but also set new standards for safety, performance, and innovation in the valve industry.
