API 600 vs API 602 dimensions in flanged valves 1

[DiegoVillanueva]

Hi, is there any dimensional difference between a 2" 150 lbs API 600 flanged gate valve and a 2" 150 lbs API 602 flanged gate valve? Can I replace an API 600 valve with an API 602 valve without making any pipeline modifications?

what dimensions you are talking about?
if you are only looking for face to face dimensions, then both API 600 & API 602 gate valves refer to B16.10 Standard. so that means face to face dimensions of valve will be same in flanged end gate valve. but there are lots of difference in the detail of the both standards.
