Magpie Valve Packing Gasket Co., Ltd

Magpie Valve (https://www.magpievalves.com/) is a research-driven leader in industrial valves, packing, gaskets, and seal kits, committed to advancing valve technology through precision engineering, material science, and third-party-verified performance. Our mission is to transform industrial valve reliability by focusing on the critical elements that govern sealing performance, a factor often overlooked in the pursuit of large-scale machining efficiency.

Recognizing that the mechanical behavior of non-metallic materials, advanced coating technologies, and friction and wear mechanisms are the true bottlenecks in high-performance valve design, Magpie Valve has prioritized these areas in its R&D efforts. Our approach goes beyond conventional manufacturing, targeting the root causes of sealing failure to deliver valves that excel under the most demanding conditions.

Our multidisciplinary team—including nuclear-grade sealing engineers, valve specialists, materials scientists, and electromechanical engineers—bridges academic insight and industrial expertise. We collaborate with leading 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 partnerships have enabled in-depth research into low-leakage graphite sealing technologies and systematic resolution of sealing challenges.

Magpie Valve’s commitment to quality is backed by rigorous testing and authoritative third-party validation. We hold multiple industry-recognized certifications, including API 622, API 624, API 641, ISO 15848-1, TA-LUFT, and ISO 15848-1 CC3. Nearly 500 valve products—from gate and globe valves to ball valves—have been tested under extreme temperatures ranging from 400°C to -196°C and pressures up to Class 2500 LB. Through these efforts, Magpie Valve not only meets international standards but also establishes new benchmarks for reliability, safety, and innovation in the valve manufacturing industry.
