Congrats on the All American PC, that is a very nice piece of equipment.  I don’t have one of those, but after looking at the parts sheet it looks like the pressure gauge is a standard 1/4” NPT (National Pipe Thread) fitting, so if it were me I would work with that.

 

The pressure cooker has a high pressure relief built in, but if you want the added security of the relief valve I suggest that you unscrew the pressure gauge and add a 1/4” x 1/4” NPT Male nipple (something like: Anderson Metals 56122) and a 1/4” Tee (something like: Anderson Metals 56101).  Screw nipple into the lid where the pressure gauge was and then the Tee to the nipple.  Finally you would screw the pressure gauge and your safety valve to the Tee.  You will need some teflon tape for all of the male treads.  Be very careful to not over tighten when screwing into the aluminum pressure cooker lid or you could strip out the threads.  You can purchase any of this from Amazon or your local hardware store.  Good luck and take care.

Not sure what you mean by 'triggers'.  The safety relief valve that you listed would open and release steam when the PC pressure exceeds 20psi.  Perhaps it would be useful if you describe what you are trying to do.

The standard AA weight regulator won't let you reach 20 psi.

it appears that the all american has a built in safety release of 18 psi

 

so it cant reach 20 psi

 

i was hoping i can pressure cook grains and wood chips a little shorter in length if i can reach 20 psi....

 

with the valve i was hoping it could maybe make a loud sound like whistling so i can leave the kitchen and do something else while waiting...

My humble advice is to use the tool like it was designed to be used.   If you want to reach higher temps/pressure then you need an sterlizer.   https://www.amazon.c...rial,257&sr=1-3

 

The unit you linked to is a canner, and its weighted gage will vent at 5, 10, or 15psi.  It was not designed to run at higher temps/pressure.

 

The jiggling of that weighted gage at 15psi will let you run your canner from the other room with no problem.  Even the hard of hearing, like myself, can hear the weight jiggling when it vents steam.

 

Again, I would advise not modifying the way your canner works.  AA is the cadillac of canners, and it will do the job you want it to.   Just relax and take the time that you need to take, to do the job you need to do.

Just what I was thinking, Juth.

Solid advise!

 

With an AA electric pressure sterilizer, you set the heat control to turn on or off the element to maintain your pressure at it's desired PSI.

So really it's not just replacing a part.

 

As Juthro said, use the tool as it was meant to be used.

 

Peace

Yeah, what's the hurry?  It's going to be a long strange trip anyway.

Glad that we could help.  I think weighted gage canners are easier to run then sterilizers anyway, sterilizers tend to need more supervision and manual adjustments.  When you find that sweet spot where the weight jiggles every minute or so you can pretty much ignore it until your cycle timer runs out.

 

Anyway, good grow vibes to you, and welcome to the 'topia :)
