The difference between cast valve and forged valve
Casting valves are valves made by casting. Generally, the pressure grades of cast valves are relatively low (such as PN16, PN25, PN40, but there are also high-pressure ones, which can reach 1500Lb, 2500Lb), and most of their calibers are above DN50. Forged valves are forged and are generally used in high-grade pipelines with relatively small diameters, generally below DN50. Casting 1. Casting: It is the process of smelting metal into a liquid that meets certain requirements and pouring it into a mold, cooling, solidifying, and cleaning to obtain castings (parts or blanks) with predetermined shapes, sizes and properties.
