Origin unknown, i beleive the reason your QEV failed is because it is a diaphram type.
the one you bought its a "poppet" type, wich uses a polycarbonate disk, aka why it can take so much pressure.
the ones from MCmaster should be able to hold 300 right?

This Is why it doesn't work now...
I took apart the QEV to sand down the sealing face so it would seal a little better at low pressures. I put it back together, but in the process I tightened the screws a little too tight and stripped the threads where the screws go in. Usually I overtighten alot of things for I am slightly compulsive. Now the air leaks out around the screws and the qev is totally useless unless I pour molten aluminum to fill the screw holes and then re-drill them. I don't have the equipment to this though...

Why don't you just drill and tap the holes one size bigger then the current bolt?

or if you don't think you'll ever want to take it apart again you could just fill it with epoxy

Unison: I would do that, but I cant use my Dad's drill press. I dont want to mess anything up either by using a normal drill.

The ball valve is acting as a "safety" .
