Magpie Valve Packing Gasket Co Ltd - China

Magpie Valve is a research-driven leader in industrial valve manufacturing, specializing in packing, gaskets, and seal kits.

We are committed to advancing valve technology by integrating deep material science, precision engineering, and third-party-verified performance.

Our mission is to redefine valve reliability, with a particular focus on sealing performance, which we believe is the cornerstone of long-lasting, high-performing valves.

In China’s evolving valve industry, large-scale machining is no longer the primary challenge.

Instead, we focus on the often-overlooked bottlenecks—namely, the mechanical behavior of non-metallic materials, advanced sealing surface coatings, and the study of friction and wear mechanisms.

These critical areas are key to achieving true valve performance excellence.

Our multidisciplinary team includes nuclear-grade sealing engineers, valve specialists, materials scientists, and electromechanical engineers.

By combining academic insights with industrial expertise, we deliver high-integrity valve solutions.

We have partnered with renowned institutions such as 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 collaborations enable us to conduct in-depth research into low-leakage graphite sealing technologies and address the root causes of sealing failures.

Magpie Valve is proud to hold numerous industry certifications, including API 622, API 624, API 641, ISO 15848-1, TA-LUFT, and ISO 15848-1 CC3 - We have rigorously tested nearly 500 valve products—including gate, globe, and ball valves—under extreme conditions, ranging from temperatures as high as 400°C to as low as -196°C, and pressures up to Class 2500 LB.

Our comprehensive testing ensures that we not only meet international standards but also set new benchmarks in valve reliability, safety, and innovation.
