Magpie Valveis a leading manufacturer of industrial valves, packing, gaskets, and seal kits, driven by research and innovation. Our mission is to redefine valve technology by focusing on the fundamentals of reliability—especially sealing performance. While large-scale machining is no longer the main challenge in China’s valve industry, we address the deeper issues: the mechanical behavior of non-metallic materials, advanced coating technologies for sealing surfaces, and the complex mechanisms of friction and wear. By tackling these often-overlooked bottlenecks, we deliver truly high-performance valve solutions.

Our multidisciplinary team—comprising nuclear-grade sealing engineers, valve experts, materials scientists, and electromechanical specialists—bridges academic research with industrial application. We maintain close collaborations with renowned 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 partnerships have enabled pioneering work in low-leakage graphite sealing technologies and systematic solutions to sealing failures.

All Magpie Valve products undergo rigorous testing and independent third-party validation. We hold globally recognized certifications, including API 622, API 624, API 641, ISO 15848-1, TA-LUFT, and ISO 15848-1 CC3. To date, nearly 500 valve products—from gate and globe to ball valves—have been tested under extreme conditions, from 400°C to -196°C and pressures up to Class 2500 LB. These efforts not only ensure compliance with international standards but also establish new benchmarks for reliability, safety, and innovation in the global valve industry.
