As a leading manufacturer of industrial valves, packing, gaskets, and seal kits, Magpie Valve (https://www.magpievalves.com/) is a research-driven enterprise dedicated to advancing valve technology through material science, precision engineering, and third-party-verified performance. Our mission is to redefine the role of valves in industrial systems by focusing on the core factors that ensure their reliability—especially sealing performance. While large-scale machining is no longer a major challenge in China’s valve industry, we have turned our focus to the mechanical behavior of non-metallic materials, advanced coating technologies, and friction and wear mechanisms—the true bottlenecks in achieving world-class valve performance.




Our multidisciplinary team includes nuclear-grade sealing engineers, valve experts, materials scientists, and electromechanical engineers, who combine academic research with industrial expertise to deliver high-integrity valve solutions. Through collaborations with top research 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 in-depth studies of low-leakage graphite sealing technologies and systematically addressed the root causes of sealing failures.




Supported by rigorous testing and authoritative third-party certification, Magpie Valve holds multiple internationally recognized qualifications, including API 622, API 624, API 641, ISO 15848-1, TA-LUFT, and ISO 15848-1 CC3. To date, nearly 500 valve products—from gate and globe valves to ball valves—have been tested under extreme operating conditions ranging from 400°C to -196°C and pressures up to Class 2500 LB. Through these continuous efforts, Magpie Valve not only meets but exceeds international standards, setting new benchmarks for reliability, safety, and innovation in the global valve manufacturing industry.
