Hi all thanks for the swift reply
As per isometric sheet, a Large female flange(pipe WN flange-8" x 600)connected to a gate valve with 8"x 600 large male WN flange..
We are going to replace this valve. We have a valve in stock but it is RF Flange with same spec of 8"x 600 Large male flange...
Can I use 8" 600 class raised face flange instead of 8" 600 class large male flange?
I couldn't find any difference in dimensions of both flanges
Anybody can please give an answer for this?
