release valve?

[mywoodshopca]

Just tried putting pressure in my pot (rated for 50lbs) and I was thinking of doing 40lbs max pressure. But on testing tonight, the release valve pops at 20lbs.. is it defective or can they be adjusted?

Thanks

Depends on the prv that you have. Some can be adjusted and others are a set pressure. What brand pot do you have?

Its a speedy sprayer 2.5 gallon pot.. I will get a picture of the valve.. Its old so I should just replace it?

I would get one rated for what you need. PRV's should work perfect and if the don't they can be dangerous.

Mine is spring loaded, you adjust a nut to suit the pressure you want it to release at.

Looked closer and peeled the paint (used pot) off the valve and its adjustable..

My pot is rated for 50lb.. so I want to use 40lb as a safe working pressure? Would I set the release valve for about 50 or so?

Curtis, what is the lowest pressure that Alumilite will work with?

Thanks Jason

35 or so is good for straight Alumilite. If you plan to do "Worthless Wood" casting, I always recommend as high as you can go.

OK, I gotta say it: That would be five pounds BEFORE the pot blows apart, wouldn't it, Curtis??? So, when your pot blows up, you'll know the exactly correct pressure!!!

NEXT POT!!!!

Maybe that should have read "As high as you can SAFELY go!"

Yep.. This will be ok for some things, but will be looking for a higher pressure pot as well

Well.. pot looks like its working :biggrin:

Pressured it to exactly 40 last night and checked it this afternoon.. still right at the same mark

Now to start working on some molds.. already got the wooden trays made..
