Features: Valves, as important control components in pipelines, are widely used in various sectors of the national economy, including petroleum, chemical industry, metallurgy, natural gas transportation, power plants, and urban water supply. In recent years, with the improvement of manufacturing equipment, new processes, new materials, and automation technology, new types of valves have continuously emerged, and the pressure ratings and size specifications of valves have also increased. At the same time, with the changing market conditions, a number of new production enterprises have developed, and the layout of existing production enterprises has also undergone significant changes. Therefore, Hefei General Machinery Research Institute has revised the "Valve Product Catalog" published in 2002. This book collects representative products from major valve manufacturers in the industry, totaling more than 2,000 models and nearly 40,000 specifications. It includes the appearance diagrams, structural diagrams, main performance parameters, main external and structural dimensions, weight, and main material of parts for various valves, as well as the manufacturers. This provides reference materials for engineering design, procurement, sales personnel, and valve users to select valves correctly, reasonably, and economically.
