Hi.. i have collected a lot of valves, and they are not the cheapest ones.
i would like to show them to you, and if you get any ideas what to build of them please tell me
I can use cnc-mill and other machining tools at work.

here is the valves and stuff.

-my english is not very good, so i wont write too much.

Hmm, another QDV. You can use much shorter ports. Do the math for the total area of the ports compared to the cross sectional area of the barrel. With short ports, a short lighter piston with less travel can be used. I use 3 ports in mine. They are twice as wide as they are tall and the port area is still almost twice the area of the barrel.

You will like the performance. Use floating o rings for a low friction valve.

lol if you were a girl I'd marry you

My suggestion - build a semiautomatic pneumatic gun (QEV + DCV + aircylinder combo)

here is one cannon that is have been designing with solidworks

What kind of gun is it? A hybrid or a pneumatic ?? Reminds me of the design I might use for a semiauto hybrid

Well it seems you've got more than enough valves to build a nice hybrid (or even a semiauto hybrid).

Hi Tech, if you remember we have been talking about that cannon with PM and chat I know the ports are not good in the pic, but i will draw new ones in the future.. i deleted the link from the post, because it confuses people from the post subject. But thaks

It looked familiar. You haven't posted much recently. Have you built one yet?

I was in the army and got out of there now... I have some parts and pipes for that qdv cannon, but I have not started yet.
