How to Modify a Sprinkler Valve

First and foremost, this video is not mine. I am uploading this video on behalf of BC Pneumatics. You can visit his site at www.bcvids.com

The most common type of valve for pneumatic cannons is the sprinkler valve. By preforming this modification, the power from a pneumatic cannon will increase much more than if the cannon were powered electrically.

Please note that I am fully aware that there is another copy of this video, however, I felt it would be best to upload this video along with the rest of BC Pneuamtics's videos. Furthermore, the author of the other video failed to site the video.

wats up with the end of the blow gun wont the

air jsut go right through and out of the opened end

[MegaSwordman]

No, it will only release a little air. There is a rubber diaphragm in the sprinkler valve as you saw in the video. When the air is released from the blowgun, it creates a vacuum that pulls up the rubber diaphragm and allows all the air to rush out through the pipe. It only takes a small amount of air to create the vacuum and this happens instantly so the air travels through the larger outlet, the barrel of your spud gun.

hey, what happens if i seal the end of my blowgun, i dont want any lost pressure when firing, althoug hit will be very minimal, i just want to make sure, also, when i drilled my solenoid, i drilled the middle and the guide rod is there, i jsut oput the thread right over the guide rod, will there be anyproblems?

[MegaSwordman]

Sealing the end of the blowgun won't do anything in terms of performance,and would most likely make it not work.

Also, the guide rod will present a problem. Unfortunately, not all sprinkler valves are made the same, and ones with guide rods are modified differently.

[angrygunsmith]

ok thanks, i just removed the guid rod altogether and it works fine, but i may neeed to make the equilization holle a little narrower...

[MegaSwordman]

Good to hear. If you have a chance, be sure to post a video of its performance.

and i wanna see this in use?

[elliotmotoX]

when putting the screws back into the valve, you should do one screw then do the screw opposite to the tightened one so you get an even seal

[Unibomber2u]

Do I have to use a cresent wrench? Ha! Why don't you get a screw gun instead of using a high speed drill to avoid stripping out all the screw heads.

Do I have to use a cresent wrench? Ha!

@chilidress it should tell in the manual

[chilidress]

how much pressure can a sprinkler afford before blowing up?

[lookin4space]

I saw another link that recommended using a pipe threader, but, if it worked for you, I'll try it.

[parker5013]

is it possible to leave the electric part in the valve and also have the blowgun so you could use it either way?

[STRIKER520]

You left out you need to plug the hole for the solenoid and I am not sure yours is the same but if you make the hole in the rubber bigger it will work better since the air wont dump fast enough the way it is.

[krbruner]

make sure you have the valve in the right direction. If you put pressure on the downstream side, it will not hold pressure.
