Magpie Valve Packing Gasket Co., Ltd Magpie Valve Packing Gasket Co., Ltd,Manufacturer
Company Introduction
As a leading manufacturer of industrial valves, packing, gaskets, and seal kits, Magpie Valve is a research-driven enterprise committed to advancing valve technology through material science, precision engineering, and independent performance validation. Our mission is to redefine the role of valves in industrial applications by addressing the core factor of reliability—sealing performance.
In today’s valve industry, large-scale machining is no longer the greatest challenge. Instead, the true bottlenecks lie in the mechanical behavior of non-metallic materials, advanced coatings for sealing components, and the study of friction and wear mechanisms. These areas form the foundation of Magpie Valve’s innovation strategy.
Our team brings together nuclear-grade sealing engineers, valve specialists, materials scientists, and electromechanical engineers. By combining academic insight with industrial expertise, we deliver high-integrity valve solutions. Collaborations 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—have enabled us to pioneer advancements in low-leakage graphite sealing technologies and to systematically resolve the root causes of sealing failure.
With rigorous in-house testing and authoritative third-party validation, Magpie Valve holds 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 ranging from 400°C to -196°C and up to Class 2500 LB. These efforts ensure not only compliance with international standards but also the setting of new benchmarks for safety, reliability, and innovation in the global valve industry.
