Magpie Valve (https://www.magpievalves.com/) is a premier manufacturer specializing in industrial valves, sealing gaskets, packing, and seal kits. Driven by research and innovation, we are committed to advancing valve technology through deep expertise in material science, precision engineering, and independently verified performance. Our mission centers on redefining valve reliability by prioritizing the most critical aspect in industrial applications—sealing performance.
In China’s evolving valve industry, large-scale machining is no longer the main challenge. Instead, Magpie Valve focuses on tackling true performance bottlenecks: the mechanical properties of non-metallic materials, cutting-edge coating technologies for sealing components, and the in-depth study of friction and wear mechanisms. These key areas set us apart.
Our multidisciplinary team—comprising nuclear-grade sealing engineers, valve design experts, materials scientists, and electromechanical engineers—combines academic insight with hands-on industry experience to deliver high-integrity valve solutions tailored for the most demanding environments.
We maintain long-term partnerships with leading research institutions such as 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. Through these collaborations, we have conducted comprehensive studies on low-leakage graphite sealing and systematically addressed sealing failure root causes.
Our products undergo rigorous testing and validation by authoritative third parties, earning certifications including API 622, API 624, API 641, ISO 15848-1, TA-LUFT, and ISO 15848-1 CC3. To date, nearly 500 valve products—including gate, globe, and ball valves—have been tested under extreme conditions, from -196°C to 400°C and pressures up to Class 2500 LB.
By setting new benchmarks in safety, reliability, and innovation, Magpie Valve continues to push the boundaries of excellence in valve manufacturing.
