piston

[roughboy]

which is more better to actuate the piston with a ballvalve or a modded sprinkler valve??

also which can take more pressure?

well, depends on the size. if you are going to use a 3/4 ball valve it will beat a 1/2-1" sprinkler.

and a ballvalve will handle way more pressure

[Velocity]

A sprinkler valve is a better pilot valve than a ball valve, because it opens a lot faster and is able to dump the pilot volume faster.

Which can take more pressure? It depends. A plastic sprinkler valve and a plastic ball valve can probably take about the same pressure. A metal sprinkler valve can take more pressure than a plastic ball valve (usually), and a metal ball valve can take more pressure than a plastic sprinkler valve. A metal ball valve can probably take more pressure than a metal sprinkler valve too.

EDIT: A few errors

[roughboy]

how about if im using a 3/8''ballvalve

[Velocity]

...it all depends on the size of your piston valve and the quality of the seal between the piston and the piston seat... there are other factors as well.
