Cast Steel Floating Ball Valve 2pcs Body Lever Operation

What are the advantages of forged ball valves vs cast ball valves, and how to choose the correct type of ball valve.
Cast ball valve is a ball valve that is cast in a mold after melting steel in a furnace.
Forging ball valve is to use forging machinery to exert pressure on the metal blank to produce plastic deformation, so as to obtain forgings with certain mechanical properties, certain shape and size.

● Casting ball valves can be cast into large diameter ball valves, and castings have higher requirements on the casting process. A feature of cast ball valves is that they can be made into more complex shapes. For valve body structure and irregular flow channel, casting can be formed at one time. Therefore, as long as the technology is passed, the large diameter valve body can be cast.
● The compactness of the forged ball valve is relatively good, because the flow channel and appearance are too complicated, it is impossible to form at one time, and it often needs to be modularized, forged separately, and connected together.
● Cast ball valves are often used for conventional pressures above DN50 and below 6.4MPa; forged ball valves should be used for DN50 and above 6.4MP for better performance.
