What is the pressure rating indicated for the stop valve as 42R, and is there a difference between old and new versions?

42 represents 4.2 MPa, and R represents material 316. It seems there’s no distinction between old and new.

It would be best if the poster could provide all the models of the stop valves. For example, 42R represents a suffix; in the case of J41H-42R, it’s as mentioned by the second poster. If that’s not the case, please share all the models for discussion
