Magpie Valve is a leading manufacturer of industrial valves, packing, gaskets, and seal kits, driven by research and innovation. Our mission is to advance valve technology by focusing on the core factors that define reliability—especially sealing performance. Rather than emphasizing large-scale machining, we concentrate on the true challenges in the industry: the mechanical behavior of non-metallic materials, advanced coatings for sealing components, and the study of friction and wear mechanisms.
