Any reason, other than expense, not to use a high temp valve as listed below?

Simplify for better results!
I recently built a 100 pounder to process WW. A 5 gallon bucket of WW weighs 130 lbs roughly, my "processor" will hold 97 lbs!! A full gallon. It too is made from things left over, like the 06 barrel that was made into the pour handle.
Anyway getting back to the valve. I simply machined a 3/4 hole in the bottom of the pot and built a fitting with a head on one end and threads under the shoulder. It went thru the bottom of the pot and has a nut on the other side. The top side of the head has a thru hole that looks like the fitting on my 20 lb pot which is simply a tapered plug. It works flawlessly. Lead is 11 times denser than water, you dont need much to contain it! Oh yea, I made those downriggers in the back ground as well.
