Is it correct as shown in the valve body material selection table?

Are the valve bodies of valves with a weight of 64 kg or more all made of forged steel?

Not necessarily; with the development of lost foam and vacuum casting technologies, CL2500-pound valves are now also generally manufactured by casting, and there are no issues in field use

For gate valves of PN64 and above, forged steel is rarely used as it is difficult to work with; forged steel gate valves are generally used for sizes of 2\" and below.
