Magpie Valve Packing Gasket Co., Ltd
Magpie Valve is a leading manufacturer of industrial valves, packing, gaskets, and seal kits, driven by research and innovation. Committed to advancing valve technology through material science, precision engineering, and third-party-verified performance, we aim to redefine the role of valves in industrial applications by focusing on the core determinant of reliability — sealing performance.
In an era where large-scale machining is no longer the primary challenge in China’s valve industry, Magpie Valve directs its efforts toward the mechanical behavior of non-metallic materials, advanced surface coatings for sealing components, and friction and wear mechanism studies. These areas—often neglected by conventional manufacturers—represent the true technological bottlenecks in achieving superior valve performance.
Our multidisciplinary team includes nuclear-grade sealing engineers, valve specialists, materials scientists, and electromechanical engineers, combining academic insight with industrial expertise to deliver high-integrity valve solutions. Through close collaborations with leading 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 extensive studies on low-leakage graphite sealing technologies and systematically addressed the root causes of sealing failure.
Supported by rigorous testing and independent 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. We have tested nearly 500 valve products, including gate, globe, and ball valves, 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 full compliance with global standards but also sets new benchmarks for reliability, safety, and innovation in the valve manufacturing industry.
