::shakes head::Judging by the name, Zero Talent probably made one. He's a member, so contact him, or go to his site.
Oh, dear.
Zero Talent was the guy who INVENTED Zero Valves..
I have attempted to make a semit-auto valve, but it leaks. Bad.
I do believe that Vntage made some valves of the like, but I'm not positive.

It's almost 3 years old, and you posted in it. Wow, you must suck a lot.
I still don't understand how it works.

I did not post in THIS thread:

BP, the valve is a simple construct that does not yield great results. Basically, it is a PVC or CPVC air tank made from a section of PVC or CPVC with plugs/caps at each end. A hole is drilled in both caps. Through this hole, a rod is fitted. This rod must plug both holes. When it is pulled one way, the other side of the rod will leave the hole in its respective cap and open the "valve" (the path between the output hole and the pressurized tank). The air will then leave through that hole. The valve is difficult to use well because the rod must slide easily and still maintain a good seal. There are better substitutes.

Will you all please shut the fuck up? Yeah, he posted in an old topic, but two of you posted with flames, one who didn't know what he was talking about, and one who actually tried to help. It's idiotic. He necroed once, now he has been told to not do it again. Now answer his question so the thread can die again.

Sorry. I did not mean to necro, I was searching for air valves and did not notice the date on the thread.
What are the alternatives to the "zero-valve"? I have seen the outline of a valve here used by a fellow called CaptainSlug that looks something like this?
I am trying to play about 3 years worth of catch up here I suppose... I am very inclined towards more simple machine mechanical things, even clockwork and and other complex machines out of simpler machines, but pneumatics always seems to confound me.

Here's the functional diagram
A = Inline Tank (low capacity for one shot)
P = Supply Tank (high capacity)
EA = Exhaust to barrel
I'm on my 12th valve design and will probably end up going through 2 or 3 more revisions before I end up with a design I'm 100% happy with. It's been a long process of trying to reduce the force load required to actuate the valve (below 5 pounds), and keep the valve design nonrestrictive in order to allow for a high flow rate at low pressure.

No that's not a functional arrangement. You need a minimum of two o-rings (three is more typical) to make a directional control valve.

ok so it works like this then?
