Where to Purchase a piston Valve?

Unread postAuthor: MICHAEL SLOAN » Mon Oct 29, 2007 8:44 am

It appears that Spud Tech is no longer selling their SGTC Supah-Valve. Where can I purchase one of these? Not sure I have the "know-how" to modify...or make one. Currently using a "rainbird,3/4" in line sprinkler valve. Sounds more like an air horn than a gun. Suspect that it is not fast enough.

HELP!!!!! :oops:

Have a look here -> yours for only $95

If you're not willing to spend that much, a properly modded sprinkler valve will only set you back $25 ;)

Yes, but the sprinkler has less than 1/4 the flow of the 95$ one, so it is really more like $100 vs. $95...

It depends on what he has in mind, for say a 3/4" marble gun a modded 1" sprinkler is more than enough.

Thanks for the responses! I am looking into the mauler valve link you sent me! Would like to shoot tennis balls. Not sure how to modify my rainbird sprinkler valve. It works pretty good....just makes a "honking" noise every time I shoot....is this is an indication of slow activation????

That or low pressure.

Instructions for modding it yourself (really easy) can be found here, here and here, see which type most resembles your valve.

A 1" sprinkler will fire a tennis ball to a respectable distance with enough pressure and chamber size through a big enough barrel, but obviously a`piston valve with a higher flow like the mauler will give better performance.

Nah, I just spend too much time here - ffs, almost 3,000 posts in 7 months :shock: Whether at work or in my room I always have a spudfiles window open, the only time I don't peek is when I'm out or asleep - even while fabricating something I tend to take small "net breaks" :D

:shock:

You can try BCArms (the official spudfiles store) http://www.bcvids.com/store/

Or you can make your own.

Sounds like you might have an addiction jack; maybe we should create a 12 step program for spudfiles addicts haha.

Anyways, If your willing to take a risk, its pretty easy to make a good piston valve cheaply, just look around.

You can buy a piston valve from almost any hardware store, its just not assembled. You have to do that part yourself.
