Top 20 Global Valve Brands

In the global valve industry landscape, China has already developed into a major valve producing country. Particularly under the impetus of the “Strong Manufacturing Country” strategy, domestic valve enterprises have continuously advanced the process of industrial upgrading in recent years and achieved a series of results, with remarkable achievements in domestic substitution. However, to be objective, China's valve industry still has a considerable gap compared with developed countries and needs to strive to catch up. Based on the principles of learning from, learning, developing and catching up, this issue selects 20 internationally renowned valve companies for review, providing a reference for industry enterprises to surpass international valve powerhouses.
