Magpie Valve Packing Gasket Co., Ltd

Magpie Valve (https://www.magpievalves.com/) is a research-driven leader in industrial valves, packing, gaskets, and seal kits, committed to advancing valve technology through cutting-edge material science, precision engineering, and third-party-verified performance. Our mission is to elevate the role of valves in industrial applications by focusing on the elements that truly determine reliability—most notably, sealing performance.

In China’s evolving valve industry, large-scale machining is no longer the primary challenge. Magpie Valve concentrates on the critical but often overlooked factors that define high-performance valves: the mechanical behavior of non-metallic materials, advanced coating techniques for sealing components, and the fundamental mechanisms of friction and wear.

Our multidisciplinary team—including nuclear-grade sealing engineers, valve specialists, materials scientists, and electromechanical engineers—combines academic insight with industrial expertise to deliver high-integrity valve solutions. We collaborate with prestigious 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 to conduct in-depth research on low-leakage graphite sealing technologies and systematically address the root causes of sealing failure.

Magpie Valve’s products undergo rigorous testing and third-party validation, earning certifications including API 622, API 624, API 641, ISO 15848-1, TA-LUFT, and ISO 15848-1 CC3. We have tested nearly 500 valve products—from gate and globe valves to ball valves—under extreme temperatures from 400°C to -196°C and pressures up to Class 2500 LB, ensuring compliance with international standards while setting new benchmarks for reliability, safety, and innovation in the valve industry.
