Unread postAuthor: thespeedycicada » Mon Aug 13, 2007 7:02 pm

After my ballvalve pneumatic cannons got belittled umpteen times i am moving on to sprinkler valves but all i have is a 1 inch valve and i want to make a golf ball cannon will the 1 inch valve affect peformance and if so how much? sorry im quite a noob with pneumatics.

Affect performance as compared to what? Any sprinkler should give much better performance as compared to a ball valve. There are things better than a sprinkler (If you can get a QEV that should be even better) but a sprinkler is a fairly easy to use and readily avaliable option that will give good power.

Well, logic dictates that a bigger one will work better, but compared to your ball valve, even the smaller sprinkler valve is better.

i know that i was just asking if the 1 inch valve im using for the 1.5 inch barrel would efect performance as opposed to a 1.5 inch valve i think paaiyan answered that though. but more details would be fine!

you know with long barrels ball valves are acually better than sprinkler valves because of the high flow.

i have used both and i personally think they are about the same. of cource my ball valves are all spring loaded and open so fest you cant see what happened, but i worked the same.

The concept is simple but actually putting it into practice involves some pretty heavy duty engineering, especially on a scale larger than 1", it's more challenging than modding a sprinkler valve. I think the latter would be the best solution in this case.

its not hard and if you cant figure it out you shouldnt build it. its litterally just a spring that pulls it open.
