Magpie Valve Packing Gasket Co., Ltd

Magpie Valve (https://www.magpievalves.com/) is a leading manufacturer of industrial valves, packing, gaskets, and seal kits. As a research-driven enterprise, we are dedicated to advancing valve technology through material science, precision engineering, and third-party-verified performance. Our mission is to redefine the role of valves in industrial applications by focusing on the core elements that determine reliability—most importantly, sealing performance.

Recognizing that large-scale machining is no longer the primary challenge in China’s valve industry, we have shifted our focus toward solving the real bottlenecks: the mechanical behavior of non-metallic materials, advanced coatings for sealing components, and the study of friction and wear mechanisms. By addressing these often-overlooked areas, we are pioneering the next generation of high-performance valves.

Our team brings together nuclear-grade sealing engineers, valve specialists, materials scientists, and electromechanical engineers. Combining academic insight with industrial expertise, we have partnered with leading 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. These collaborations have enabled us to conduct deep research into low-leakage graphite sealing technologies and systematically resolve the root causes of sealing failures.

Backed by rigorous in-house testing and authoritative third-party validation, Magpie Valve holds globally recognized certifications such as 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 from 400°C to -196°C and up to Class 2500 LB pressure ratings. These achievements not only ensure compliance with international standards but also establish new benchmarks for safety, reliability, and innovation in the global valve industry.
