 Magpie Valve is a leading manufacturer of industrial valves, packing, gaskets, and seal kits, driven by research and innovation. Our mission is to advance valve technology by addressing the core factors that determine reliability—chief among them, sealing performance. While large-scale machining is no longer the primary challenge in China’s valve industry, we have focused on solving the true bottlenecks: the mechanical behavior of non-metallic materials, advanced coatings for sealing components, and the study of friction and wear mechanisms. By concentrating on these critical areas, we redefine what high-performance valves can achieve in demanding industrial environments.
Our multidisciplinary team brings together nuclear-grade sealing engineers, valve specialists, materials scientists, and electromechanical engineers, merging academic insight with practical expertise to develop high-integrity valve solutions. We maintain long-term collaborations with renowned research institutions, including the National Key Friction Laboratory at Lanzhou University of Technology, Ningbo Institute of Materials, East China University of Science and Technology, and the Shanghai Institute of Ceramics. These partnerships have enabled us to conduct in-depth research on low-leakage graphite sealing technologies and systematically address the root causes of sealing failures.
Every Magpie product is backed by rigorous in-house testing and authoritative third-party certification. Our valves hold industry-recognized approvals such as API 622, API 624, API 641, ISO 15848-1, TA-LUFT, and ISO 15848-1 CC3. To date, nearly 500 valve products—including gate, globe, and ball valves—have been validated under extreme conditions ranging from 400°C to -196°C and pressures up to Class 2500 LB. Through these efforts, Magpie Valve not only ensures compliance with global standards but also sets new benchmarks for reliability, safety, and innovation in valve manufacturing.
