Has anyone seen this valve?

Unread postAuthor: jcinco101 » Wed Sep 23, 2009 7:21 pm

Looking to expand my cannon but I can't find this valve. Does anyone know where to purchase or the name of this valve. It has M7 on one side and A, B and C on the other. It has PILOT stamped on top.

Thanks in advance,

~jcinco101

Sorry, I thought both views attached, my friend sent me these closeups from a cannon he saw.

Thanks for the replies!!

You posted the same photo M7 twice. Can't really tell from just the one close up of part of the valve.

here is another view, I only have these closeups a friend took these from a cannon he saw. I can probably get more.

Thanks for the replies,

so i take it your looking for a pnuematic cannon valve? the valve shown appears to be similar to a sprinkler valve. and why not just make your own piston valve and get alot more power?

As above, it doesn't seem to function any differently from a common sprinkler valve, and the latter will probably give you more flow. I don't think it's work seeking out this particular type of valve.

I don't recognize the make or model. It does look like an air operated diaphragm valve. Most likely due to the air control (unless modified for it) this is an industrial control valve for an automated process. The hints are the mounting feet for installation to a bulkhead. This valve is meant to be supported in normal use unlike a sprinkler valve. It is possible the valve is designed for higher pressure than a sprinkler system. The body construction and thick end plates indicate this. I doubt you will find one outside of process equipment manufactures. This is not a plumbing supply item.

Thanks for the replies, I like its metal construction and in-line construction. All the quev's that I've found othe than a sprinkler valve are designed to be used at a 90•.

Thanks

Normal sprinklers are inline, so you will need to add two elbows.
Why is this, besides the cost for extra fittings, bad?
-The elbows may constrict flow. But sprinklers have a very crappy flow by themselves, so this wouldn't matter much.
-If the sprinkler was but behind the elbows (at the chamber) there would be a lot of dead space.
-If the sprinkler is put on the top side, between the elbow and the barrel, this shortens your barrel (or makes your launcher longer).
