Company Information
| Company Introduction : | About Magpie Valve Magpie Valve is a leading manufacturer of industrial valves, packing, gaskets, and seal kits, driven by research and innovation. Our mission is to redefine valve performance by advancing the science of sealing—a critical yet often underemphasized factor in valve reliability. While large-scale machining is no longer the primary challenge in China’s valve industry, we focus on the real performance bottlenecks: the mechanical behavior of non-metallic materials, advanced coating technologies for sealing surfaces, and the underlying mechanisms of friction and wear. At the core of our company is a multidisciplinary team of nuclear-grade sealing engineers, valve design experts, materials scientists, and electromechanical specialists. Together, we combine deep academic knowledge with industrial application to deliver high-integrity valve solutions for demanding environments. Magpie Valve collaborates closely 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 us to conduct in-depth studies into low-leakage graphite sealing, coating reliability, and long-term wear resistance—ultimately helping us tackle the root causes of sealing failures in industrial valves. We have tested nearly 500 valve types—including gate, globe, and ball valves—under extreme temperature conditions from -196°C to 400°C and pressures up to Class 2500 LB. Our products meet or exceed stringent global standards and have passed certifications such as API 622, API 624, API 641, ISO 15848-1, TA-LUFT, and ISO 15848-1 CC3. Backed by third-party validation and rigorous testing, Magpie Valve continues to set new benchmarks for sealing performance, reliability, and safety in industrial valve manufacturing. |
