Pump Casing refer to the components of valves that are manufactured through the Casing process. These Casing are integral to the construction and operation of valves, which are mechanical devices used to control the flow of fluids (liquids, gases, or slurries) in piping systems. Valve parts castings are produced using various casting methods, including investment casting, sand casting, die casting, and others, depending on the material, complexity, and specifications of the valve component.
