http://australia.rs-online.com/web/sear ... &R=3896747

If the link doesn't work, search P4Q-CA16 on RS-Online Australia.

Never bought from them before so i'm not sure if you need a company account or if they let anyone buy from them. Could be cheaper on eBay, who knows.

Edit: They provide you with a CV value if you want to calculate it in GGDT, 7.3, which is more than a 1" sprinkler valve last I checked.

They are wanting $61 for it :/ i was thinking more of something like this:
http://www.ebay.com.au/itm/Pneumatic-3- ... 098wt_1139

or this:
http://www.ebay.com.au/itm/Pneumatic-Qu ... 1408wt_905

but im worried because it can only hold 145psi and i want it to atleast hold 250psi or more :/

EDIT: Also do you know where i can buy a 3 way valve?

they hold more than what they are rated for, lots of people use them for 250 up to 500 max or so but getting any higher would be better to make your own piston

I have made my own piston but there is always something going wrong with it plus it would be cheaper to buy a QEV than make one but depending on the size and maybe quality.

Its good to hear that if i buy one i can take it up to at least 300psi :D

Why do you care what it looks like? They all do the same job.

And yeah...they are going to be expensive in Australia. You could always just make your own valve.

Anyway, the QEVs are probably fine to use at 500PSI, people have used them at up to 800PSI I believe.

You can get a 3-way valve from the same website I linked you to.

they are much more expensive if you go to a pneumatic place in aus(like festo, norgren or parker) i ask the guys at festo they wanted 75 for a 1/2'' qev.

get it off eBay, look around a bit you can sometimes find a really good deal and yea my 1/2'' valve has 120psi rating and i have used it at 600 shit loads.

you can get 3ways off ebay as well the cheapest ones are slide check valves use for paint ball about 9bucks, but make sure if you get one to tell they guy to label the packet with out the word paint ball. something like pneumatic valve

I know they do they same job but i want QEV that's more compact than some chunky QEV that gets in the way of when aiming :)

@Crna legija I found some 3 ways that i might buy but im not sure but do any of these look decent?

http://www.ebay.com.au/itm/Replacement- ... 363wt_1139

http://www.ebay.com.au/itm/New-Paintbal ... 2eb55246f3

http://www.ebay.com.au/itm/3-8-NPT-2-Po ... 347wt_1139

i was thinking of buying the first one (the first link) because it looks like is has more air flow than the other ones. correct me if im wrong.

Actually the last one (3/8") probably has more flow because of the larger diameter. The first one is only 1/4".

I wouldn't get the fist one, i have one build in the same way and it leaks at 150, the 3rd one is a 2way valve but i think it pilots though the hole in the brass rod and the second is fine only problem with them is you have to rig some trigger for it

the first and 2 are 3ways just the slide check valve doesn't have a threaded port for its 3 i think the 3rd on is the same, Mc master don't ship down under.

I think I heard somewhere that the second one you linked to is used for venting and has really tiny holes so it wouldn't be good for a pilot.
