Yeah that's probably not worth it. I picked up a concoa dual stage for $65 today. I will probably just keep looking on fleabay for a back up

Parts are relatively cheap.. What I'm a bit confused about is that the relief valve should be on the lp side and not be like 400#
I seem to be missing something here..

I believe the relief valve on the victor dual stage is between stage 1 and stage 2. Stage 1 is supposed to drop the pressure to 400 psi and then stage 2 lowers it to whatever pressure you set it at. Since the first stage is blown, it is sending all of the pressure(800 psi) to stage 2 and that is why the pressure relief valve is bleeding off the pressure

Well the way I see it it is the high pressure side sets the high pressure..

I'd think the LP side failed.. It is the one regulating what the safety valve sees..........

Sorry just a need to understand basis..


According to this: There are 2 which I don't see either..

Two stage regulators have two safety valves
so my take from this thread and this one:
http://weldingweb.com/showthread.php...ulator-problem

Is the Victor only has a HP relief valve...... Hmmmm...

How about this:
Quote:
Don't buy any of that, just take the relief valve off and buy a 1/4" NPT plug for $2 and put that in instead. You don't need a relief valve....

Exactly. I am not trying to be arrogant, for the record you brought it up, but I build and sell these and know a lot about them. They are not needed, and furthermore, I would definitely be concerned about a liability, that goes to show that it is not a liability.

Point seems to be is that the hp stage is not limiting intake to under 500 psi.. Most CO2 tanks if I remember correctly are '"natively" 800psi or so, though when "heated" can go much higher but I'm not sure it would get to burst strength of the tank....besides the tank valves have their own relief valve.


So it seems like, yes 1st stage is not regulating..second stage is.. Plugging the safety valve could be "ok".. Finding one that is 800psi could be ok too.. (800 psi bUT the highest I found is 600# http://weldwarehouse.com/cgi-bin/ein...:341=0600-0025)

Biggest catch is you now have a 1 stage regulator.........

Unscrewing the HP cap doesn't seem that problematic.. 1 9/16th or so wrench and a good vise..

considering all of the above.. The question arises "what if" the LP side fails?..
There is nothing stopping 500# from going into the CO2 tubing ect...

No relief valve.. Seems "we" should be thinking about this.. especially for those doing in line or reactors.. Potential for catastrophic water leakage..

anyone else seeing this way?? Or an I off base somewhere?

YES I now see that it must be the HP side btw.. I was thinking the relief should be on the LP side, which it isn't..
