hello, some of you might know me from air power.net, anyway i just bought a qev off mc master carr and then bothered to read the description
it was rated to 477 psi! now i dont know what the hell to do with it, i was thinking i should solder a copper cannon together and use the high pressure ability, any suggestions? :? heres the link: oh wait never mind, just search for'quick exhaust valve' and click on exhaust control valves. by the way i do not consider myself a noob i have made lots of cannons. :wink:

you should give us the link, im not finding anything rated for more than 150 psi
in the upcoming presidential election, there will be several candidates who will be running, one of whom is Hillary Clinton. Now WAIT A SECOND!!! I though there was some sort of rule that prevented someone from serving more than two terms in office. Vote Against Hillary: Presidential Elections 08

But why did you post your question to thread that is 10 years old one..
Valve probably is ok, but I think it will cost very much if you buy a new one. Some people here have used standard qevs up to 400psi with no problems, but depends on the exact model and size.
