Magpie Valve (https://www.magpievalves.com/
) is a leading manufacturer of industrial valves, packings, gaskets, and seal kits, driven by research and innovation. As a technology-oriented enterprise, we are committed to advancing valve performance through deep material science, precision engineering, and third-party-certified testing.
Our mission is to redefine valve reliability by focusing on its most critical aspect—sealing performance. In today’s industry, where large-scale machining is no longer the main challenge, Magpie Valve prioritizes the mechanical behavior of non-metallic materials, advanced coatings for sealing components, and the study of friction and wear mechanisms—areas often overlooked but essential to achieving high-performance, long-lasting valves.
Our multidisciplinary team includes nuclear-grade sealing engineers, valve specialists, materials scientists, and electromechanical experts. Together, they blend academic insight with industrial experience to deliver high-integrity valve solutions. We collaborate with renowned 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. These partnerships enable us to conduct in-depth studies on low-leakage graphite sealing technologies and systematically eliminate the root causes of sealing failures.
Supported by rigorous in-house testing and authoritative third-party validation, Magpie Valve holds multiple internationally recognized certifications, including API 622, API 624, API 641, ISO 15848-1, TA-LUFT, and ISO 15848-1 CC3. To date, we have tested nearly 500 valve models—covering gate, globe, and ball valves—under extreme temperature ranges from 400°C to -196°C and pressures up to Class 2500 LB.
Through continuous research and technical excellence, Magpie Valve not only ensures full compliance with global standards but also sets new benchmarks for reliability, safety, and innovation in the valve manufacturing industry.
