I want to make a metal cannon using 250psi but what kind of valve should i use that can handle 250psi?-----THANX

home made piston,you would have to make it uber strong though.
im pretty sure QEVs can handle 250psi,they might do but i cant tell as i havnt used one.

Some QEVs (quick exhaust valves) are rated to 250 psi but most are only rated to 125-175 psi.
