so im lookin for a 300+psi dump valve i would like it to be metal but if not its cool but i cant find one online only the rain bird ones that are like 150 psi max so if you know where i cant get one or if there is even one out there

What?

You surely mean a solenoid valve.

You can get ones for 300psi pressure and they are generally metal and very definitely expensive. Not very findable mind you.

Hey I found one: http://www.patriot-supply.com/products/ ... .cfm/48499

Bloody expensive. I'm sure there are cheaper ones out there.

Found another, cheaper one:

Doubt you'll find a new one for much under $150.

Make your own all metal piston valve. Not too hard, just takes some work.

Since you mentioned not wanting to have to do much in the way of modding you might want to take a look at quick exhaust valves (QEV's).

Technobots declares them to be useable to 300psi and they use them in combat robots.
