Magpie Valve is a leading manufacturer of industrial valves, packing, gaskets, and seal kits, driven by research and innovation. Our mission is to redefine the performance standards of industrial valves by focusing on the core determinants of reliability—especially sealing integrity.
As China's valve industry matures beyond the challenges of large-scale machining, Magpie Valve has shifted its focus to more advanced frontiers: the mechanical behavior of non-metallic materials, precision surface coatings for sealing components, and the science of friction and wear. These often-overlooked factors are the true bottlenecks in achieving ultra-reliable valve performance.
Our interdisciplinary team includes nuclear-grade sealing engineers, valve experts, materials scientists, and electromechanical engineers. By blending academic insight with hands-on industry experience, we develop high-integrity solutions tailored for demanding environments. We collaborate closely with renowned research institutions, including the National Key Friction Laboratory at Lanzhou University of Technology, the Ningbo Institute of Materials, East China University of Science and Technology, and the Shanghai Institute of Ceramics. These partnerships have fueled in-depth research on low-leakage graphite sealing and helped us systematically resolve common failure mechanisms in sealing systems.
Magpie Valve’s commitment to quality is backed by rigorous testing and verified by leading third-party organizations. We hold certifications such as API 622, API 624, API 641, ISO 15848-1 (including CC3), and TA-LUFT. To date, we have tested nearly 500 valve models—from gate and globe to ball valves—under extreme temperature conditions (from -196°C to 400°C) and high pressures up to Class 2500 LB.
By setting new benchmarks in reliability, safety, and sealing performance, Magpie Valve continues to lead the evolution of valve technology for critical industrial applications.Know more about China Manufacturer
