May I ask the experts, what is the difference between cast valves and forged valves?
Cast valves are made by casting, and forged valves are made by forging, right? Just look up the difference between casting and forging, right?
When are cast valves used, and when are forged valves used?
Cast valves are produced by casting, and generally, valves made in this way have low pressure levels, such as 16. 25.40 Forged – that is, produced by forging; used in high-grade pipelines
More support for the 5th floor, hehe! Just look at their respective scopes of application to find the difference!
What was said on the 5th floor is very accurate. From my personal experience, if casting can be used, then forging isn’t necessary; forging is much more expensive. Additionally, it’s easier to forge small-diameter pipes, while larger-diameter ones – such as those over 300 millimeters – are not so easy to forge, and even if it’s possible, the cost becomes extremely high
Is it correct that valves with a diameter of DN50 or larger are cast valves, while those with a diameter of DN50 or less are usually forged? Also, only valves with a diameter of DN50 or less can have their parts welded together; valves with a diameter larger than DN50 are cast as single units, so there is no issue with welding. Is that correct?
What was said on the fifth floor is very accurate; however, those with a diameter of DN50 or more can also be welded!
It is generally classified as cast for DN50 and above, and forged for DN50 and below.
Are there welded valves available for sizes larger than DN50? 10# Jiangtai People
