Has anyone had any experience in modifying a brass sprinkler valve. Here is a link to the store.

Here is a diagram of the parts.

I am guessing it will be similar to modifying a plastic valve but want to make sure as this would be an expensive mistake.

If you are willing to spend that much money, I think a better investment would be an ASCO 8353 Series with an air actuated pilot.

These are pulse valves. A few years back, myself and others on the forum purchased some for a reasonable price of about $18.

Here are some links to some of the cannons;

I'm looking at the one dewey mentioned, would be a lot easier. Just wish it was in-line but o well, can't be picky. The tech guy told me that is was a 5 psi minimum and would not work. Said had to be 5psi to close valve after firing, pretty sure he is wrong.

Here is the spec sheet for ASCO 8353 Series;

8353H038 has the remote air pilot option.
That is the one you see on the example cannons.

Anyone have experience in piston valves like this? 53cv for $85. Looks like it has a 1/8" npt valve to open chamber.

As mentioned above a QEV would be better and more cost effective than a metal sprinkler.

But if you really want an inline valve...I happen to have a 2" plastic sprinkler valve laying around from an old golfball launcher that I need to sell :D
