Cast steel valves and forged steel valves are steel valves, so what are the differences between them?Cast steel valves and forged steel valves are easy to distinguish in appearance. Cast steel valves are silver in appearance and forged steel valves are black in appearance.
In addition to the differences in appearance and color, what are the essential differences? Here’s a brief introduction.
- First of all, cast steel valves cannot be acid and alkali resistant and it can only be used on ordinary pipelines, while forged steel valves can withstand high pressure. It can be used in some high temperature factories, such as power plants and chemical plants.
- Secondly, the structure of forged steel valve is much finer than that of cast steel gate valve, showing better performance in mechanical properties. The structure obtained by casting is a structure with coarse grains, and the fine grains obtained by forging. In another popular way: the mechanical properties of forged steel gate valves are good, and the toughness is stronger. If the components are the same, the corrosion resistance of the forged steel is high, and the bearing capacity is high. Compared with cast steel, it has obvious superior performance.
- Price difference. The price of forged steel valves is also much higher than that of cast steel gate valves. It’s better to choose the suitable valve according to different needs to make every amount of money produce the greatest value.
- The difference in valve caliber. Generally, cast steel valves can be produced from DN15-DN1000, while forged valves are generally produced only from DN15-DN50.
