<div align="center">MINI PNEUMATIC

This is a small pneumatic that I use to shoot AA batteries, fire crackers, potatos, bolts, darts, water, and whatever else I can find. The chamber is made from 1.5" sch-40 PVC and the barrel is .5" sch-40 PVC. The ball valve is .5" and opens easly and smoothly. To fill the chamber, I inserted an automotive schrader valve into the end cap. The chamber is rated for 330psi, but the most I have put in it is 180psi, with this much pressure and a quik flip of the valve, I can shoot a bolt through a metal coffee can.

very nice design, and the metal ball valve looks good on it, and a sprinkler valve won't fit as far as I know... (no 1/2" sprinklers)

you could go with a 1/2" asco solenoid valve or a 1/2" QEV

With a couple of bushings you could go from a 1/2 pipe to a 3/4 sprinkler valve, it could be a couple bucks, but going from 3/4 to a 1/2 would really constrict flow.

Do they make smaller selinoids? They proably do but they might be for another application.

I think that the smallest is a 1/4 in solenoid valve by Asco.

no, i've seen 1/8" solenoids, and a 1" probably wouldnt be in the way, just put it before the elbows, it should fit

I ment do they make them more compact so there is not a thing that sticks out on the top. Thats what I dont like about selinoids there to bulky.

Or you could pneumatically mod the valve, although on the Asco's I don't think it's possible. By modding it you'd get rid of that ughly solenoig.

i think it depends on the size of the asco, the big ones can be modded, i saw a few chewy modded

the smallest solenoid valves ive ever seen is 13mm it has 15mm threads on one side and a 13mm barbed fitting on the other im thinking of buying one but modding it would be hard because the whole top cover is the solenoid!! i might have to make a new top for it from plastic sheet

the thing i dont like about these 13mm valves is that they want me to buy them in a two pack for $45 and i only need one :x
