What's is a slide valve, and how does it work in relation with a QEV. What type of slide valve do i get to work with this: http://www.ebay.com.au/itm/Pneumatic-3- ... 231272a898

My air supply will come from a 50mm galvanized steel pipe (as a stock)

What's is a slide valve, and how does it work in relation with a QEV.

Basically something like this:



When the valve is in the forward position, it allows air to flow from the main supply to the QEV and fill the pilot and firing chamber.

When the valve is in the rear position, two things happen:

- main supply is cut off

- QEV pilot chamber is open to the atmosphere, emptying it and firing the launcher

The valve goes back to the forward position (you need to add a spring or do it manually) and the cycle can be repeated.

Here's a nice 3/4" slide valve: http://cgi.ebay.com/Deltrol-SL35-3-4-Sl ... 2eb4b3739c

You could also get a cheaper 1/8" one and use an adapter: http://cgi.ebay.com/New-Paintball-Gun-S ... 2c5cefe367

hey mate, love the design on it
I'm from Australia too, got myself a soda stream canister and I machined a hammer valve too, but what I wanna ask is where the heck do you get .25 steel tubing?

But what I wanna ask is where the heck do you get .25 steel tubing?

I don't know about steel, a steel supplier would be the way I'd go, but for brass and aluminium tubing I'd go to a hobby shop or Toyworld. I won't be buying 4.5mm ID aluminium for a while since I picked up 15 meters for $15.

Can I ask what state you're in?

[jazzman56]

Zeus, any chance of getting some of that 4.5mm Aluminium off you?
I have looked everywhere to find 4.5mm ID but still haven't found anything suitable yet.
