I would like to replace the K valve on my AL80 with a J valve and I've found a few on Ebay. My question is this: Do all 3/4" J valves handle 3000 PSI or not?

I like J valves. I learned to dive using them and, when using my single hose regs with SPGs, I like the backup. Also, I just bought a DA Aquamaster and I want to dive it the way I did in the old days. I have a Healthways steel 72 with a Sherwood J valve and it has served me well for over 30 years.
I have an aluminum 80 with a J-valve that I want to replace with a K-valve. Trade? PM me.
