As a leading manufacturer of industrial valves, packings, gaskets, and seal kits, Magpie Valve is a research-driven enterprise committed to advancing valve technology through material science, precision engineering, and independently verified performance. Our mission is to redefine the role of valves in critical industrial applications by focusing on the factors that truly determine long-term reliability—most notably, sealing performance.
In an era where large-scale machining is no longer the primary challenge within China’s valve industry, Magpie Valve has strategically shifted its focus to the industry’s real performance bottlenecks. These include the mechanical behavior of non-metallic sealing materials, advanced surface coating technologies, and the fundamental mechanisms of friction and wear. Often overlooked, these elements are essential to achieving genuinely high-performance, low-leakage valves.
Our multidisciplinary team brings together nuclear-grade sealing engineers, valve design specialists, materials scientists, and electromechanical engineers, combining rigorous academic research with deep industrial experience. We maintain long-term research collaborations with leading institutions such as Lanzhou University of Technology’s National Key Laboratory of Friction, Ningbo Institute of Materials, East China University of Science and Technology, and the Shanghai Institute of Ceramics. Through these partnerships, we have conducted systematic investigations into low-emission graphite sealing technologies, identifying and resolving the root causes of sealing failure at a fundamental level.
Backed by comprehensive testing and authoritative third-party 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. Nearly 500 valve products—ranging from gate and globe valves to ball valves—have been tested under extreme operating conditions, with temperatures from –196°C to 400°C and pressures up to Class 2500 LB. These efforts ensure not only full compliance with global standards, but also establish new benchmarks for reliability, safety, and technological innovation in the valve manufacturing industry.
