no not at all. most sprinkler valves you would be lucky to get 250 psi. what kind of a gun are you planning on building then you can get some more in depth answers. you could try a metal piston that'd take 400 + psi
Yea, that's definitely going to get you at least a tazer.

I'm planning on making a metal pneumatic because I'm in snow.
So if i make a piston valve, what would i use to release the pressure?
Isn't that what you need to do? I really don't know, this is my first time making one.
I think he's talking about what to use for a pilot vent valve on a 400 psi piston gun. If you are talking about a pilot valve, not a main valve, do what I did: use a pressure washer handle. You can buy them relatively cheaply from McMaster, and they offer 3/8" porting and a trigger-like grip.
If you're talking about a main valve, a triggered burst disk would be the cheapest option, but not the easiest to work with. Some solenoid valves are rated for over 400 psi, but they're expensive. Apparently, high pressure QEVs (essentially piston valves with quality control) are available also, but I have no idea where one would go about obtaining such a thing - possibly a large hydraulic supply.

it should work. depending on the size of the valve you are piloting it might not have enough flow but it should so try it and get back to us on if it works or not

Unless it is a *really* crappy pressure washer handle, it should have far more flow than any blowgun, modded or otherwise. Unfortunately, judging by the look and price tag of that handle, it may well fall into the really crappy category. Try McMaster, if you live in the states.
Also, make sure of the inlet fitting on the handle. It should be 1/4" NPT (or 3/8" for a really good one), but it would be better to know before buying anything.

On mcmaster, it's like 50$ for one and that kind of my budget for the whole cannon Confused so i don't know if this cheap one will work...
What calibre were you planning on using? Because if you're careful with your pilot volume, you can successfully pilot with a schrader valve, the same one you use for filling. I've done this with a 1 inch piston and it worked great.
