Question:

what should be the gate valve class for the pipe design pressure of 25 bar ?

I wanted to know the rating for post indicator valve whose dia is 500mm in a firewater pipeline in petrochemical plant. The material of the pipe is carbon steel, CLASS 150, design pressure is PN 25, working pressure is 12 bar. Can anyone specify me the guideline to decide the flange rating for gate valve?

If you saved all of that to your SIM card then yeah you'll have it all on your new phone. But if you didn't, then take your old phone (if it's not completely broken) to the Verizon store with your new phone and they will transfer everything for you.
