You can put up to like 14kgs in them i think. Search Chris Cartaya on youtube. He has a few videos on it.

okay I read through both the posts and I think that I understand the set-up. Now correct me if I am wrong but I wont need check valves as I am not staging my tank refilling. At the moment I just own the big salvo (working completely fine) and the big bad bow. So I presume that I just need the button, tubing and connector T's and elbows? Also I don't know if you can help but I only have one more reply left so after that I wont be able to continue this discussion. Is there any way that I can speed up this approving? thankyou very much for your time and help towards a fellow nerfer.

Captain slug I would basically like to fire them both at the same time. I do have the original trigger yet I would like to activate then both at once as it sounds less complicated. so in reply to your question I would chose option #2 to use a push button valve. I haven't any access to a hornet or any other nerf type blast button so I will need to buy a proper push button. The two tanks will be placed on the clips of a big bad bow and then the aim is to have the push button on the side of the gun. I don't really have a schematic for this so I just kinda need to know what push valve to use and the tubing and connectors. 

So would one of these work? Clippard MAVO-3 3-Way Stem Valve then put in in the place of the trigger valve already on the big salvo. Thankyou for replying all, just newbie rules wouldnt let me post a reply to your comments for over 1 day. I dont know how to resolve this though.

Do you know what these buttons or valves are known as though? Links or names would be great
