Founded as a leading manufacturer of industrial valves, packing, gaskets, and seal kits, Magpie Valve is a research-driven enterprise committed to advancing valve technology through material science, precision engineering, and third-party-verified performance. Our mission is to redefine valve reliability in industrial applications, with a particular emphasis on sealing performance—the critical factor in valve longevity and safety.
In China’s evolving valve industry, large-scale machining is no longer the primary challenge. Instead, we focus on the mechanical behavior of non-metallic materials, advanced coatings for sealing components, and the study of friction and wear mechanisms. These often-overlooked areas are the true bottlenecks in achieving high-performance valves.
Our team combines the expertise of nuclear-grade sealing engineers, valve specialists, materials scientists, and electromechanical engineers. Collaborating 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 conduct in-depth research into low-leakage graphite sealing technologies and systematically address the root causes of sealing failures.
Magpie Valve maintains rigorous testing standards and holds multiple internationally recognized certifications, including API 622, API 624, API 641, ISO 15848-1, TA-LUFT, and ISO 15848-1 CC3. Nearly 500 valve products—from gate and globe valves to ball valves—have been tested under extreme temperatures from -196°C to 400°C and pressures up to Class 2500 LB. Through these efforts, we not only ensure compliance with international standards but also set new benchmarks for reliability, safety, and innovation in the valve industry.
