Magpie Valve Packing Gasket

Magpie Valve  is a leading manufacturer of industrial valves, packing, gaskets, and seal kits, driven by research and innovation. We are dedicated to advancing valve technology through material science, precision engineering, and third-party-verified performance, with a clear mission: to redefine the role of valves in modern industry by improving their most critical factor—sealing reliability.

Unlike traditional challenges of large-scale machining, today’s real bottlenecks lie in non-metallic materials, advanced coatings, and friction and wear mechanisms. At Magpie Valve, we prioritize these overlooked areas to deliver solutions that achieve true high performance.

Our team brings together nuclear-grade sealing engineers, valve experts, material scientists, and electromechanical engineers—a unique blend of academic research and industrial expertise. Through collaborations with top institutions, including 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 pioneering research into low-leakage graphite sealing technologies and systematically addressed the root causes of sealing failures.

Every product is backed by rigorous in-house testing and validated by authoritative third-party 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—from gate and globe valves to ball valves—under extreme conditions, with temperatures from 400°C down to -196°C and pressures up to Class 2500 LB.

Through this commitment, Magpie Valve not only ensures global compliance but also sets new benchmarks for reliability, safety, and innovation in the valve manufacturing industry.
