[0002] Valves and fittings are key control components in fluid delivery systems, and their quality and performance directly affect the safety, efficiency and reliability of the entire system. Valves and fittings are used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium (such as temperature, pressure and flow). They are an indispensable part of the fluid delivery system. In the production process of valves and fittings, grinding is a necessary link to remove burrs, uneven parts and other defects generated during the casting process, and improve the surface quality and precision of valves and fittings.
