ok i have to know witch pilot valve is the best
a blow gun or hammer valve to pilot the barrel sealer that i want to build ?
because if it not have a pig different with the performance i will choose the blow gun
the pressures i talking about 400-1000 psi hpa
thanks
witch pilot valve is the best
youll have better results if you look on here rather than google, a hammer valve is homemade you cant buy themSparkie wrote:Can you buy a blow gun rated to that?
What is a hammer valve...Google only gives me crap about half life 2

Far Cry;
A "standard" blow gun is not safe at 1000psi.
I've tested a few of the blowguns which I use on my projects, and will not use them past 450psi.
That is why I chose to pilot the co-ax with a hammer valve. A decent trigger pull was a bonus as well.
You could however, try a pressure washer handle. Most are rated in excess of 2000psi.

I suggest not using witches, they're too temperamental to be pilot valves.
Stay away from warlocks for the same reason.

On a more sensible note, I would point out that hammer valves and blowguns are used for different reasons.
If you only need a single shot from the chamber, go with a pilot valve that will dump air efficiently for as much power as you can extract. If you need multiple shots, you'll have to go with the hammer valve.
Next I want to know is what former experience you have with successfully storing and handling lower pressures. So far, you have not provided a great many examples of your work, so I have a nagging doubt about whether it's sensible for you to be using pressures of the magnitude you're suggesting.

Does that thing kinda look like a big cat to you?
A hammer valve can give one shot if driven by a spring powerful enough to not only open the poppet through sheer force but hold it open until the gas pressure is exhausted.
I believe Gippetos hammer valve cannon works in that way. Also that he's going to have fun getting a spring setup to operate it at the designed pressure of 3000psi not the currently working 600psi. But best of luck
Back to here and now, a hammer valve will work for those pressures. As long as you can make it.
Blowgun... Well it probably won't fail due to the pressure but I personally would be dammed before I used a mass produced £2.50 aluminium valve created with the expectation that it would be used at no more than 150psi to guarantee the security of a cannon holding 1000psi.
What are you thinking of using it for anyway.

thank you for the help and that good ideaGippeto wrote:You could however, try a pressure washer handle. Most are rated in excess of 2000psi.
that exactly what i want "spring powerful enough to not only open the poppet through sheer force but hold it open until the gas pressure is exhausted" of course for the pilot area not the chamberHotwired wrote:A hammer valve can give one shot if driven by a spring powerful enough to not only open the poppet through sheer force but hold it open until the gas pressure is exhausted.

and i thinking of using it for air gun
you miss the point , i dont need hammer valve as main valve (pcp) , i just want it to pilot the piston valve fast and efficiently.Ragnarok wrote:If you only need a single shot from the chamber, go with a pilot valve that will dump air efficiently for as much power as you can extract.

so Gippeto my question is , if i use hammer valve to pilot the piston valve ,did the performance increase than if i use pressure washer handle to pilot the piston valve????
I know that - nothing I said is specific to that it being the main valve. It's possible to pilot a well made piston valve or a QEV with a hammer valve and still get the multiple shot characteristic of the hammer valve, by virtue of exhausting the pilot a bit at a time.far_cry wrote:you miss the point , i dont need hammer valve as main valve (pcp)
And in answer to your question - if you're dumping the entire pilot, there will be no functional difference between the power provided by the hammer valve piloting and the power provided by any other type of piloting, as long as one variety is not providing vastly more flow, which I can't see being hugely likely.

check out what i posted just a few minutes ago. it's a mechanically triggered pop-off. if u use it for a single fire cannon then all that stuff i typed won't really apply to u. best of all it can have as high of a pressure rating as u need depending on how u make it (which is pretty simple and easy). it feels more like a real trigger. it opens instantly so u wont have to worry about opening a valve quick enough by hand for a proper pilot.

By nature, a QEV is an avalanche type valve. Expecting it to suddenly close before the chamber has mostly emptied is a pipe dream.Ragnarok wrote:I know that - nothing I said is specific to that it being the main valve.
