DN25 Globe PN40 RF A105 STL-STL J41Y-40; in this globe valve, the material A105 is used for which part of the valve? If we want to use a domestic material instead, how should we do that? How do I check it? Could the seniors please explain in detail? Also, for Full THD SB/NUT A193.B8 CL.2/A194.8 (S1) studs and nuts, what grade should be chosen? :handshake:handshake:handshake
