I'm thinking about using 4 valves in parralel to make a high pressure golf ball cannon. 4 of these 3/4" QEV should have slightly more circular area than a single 1.5" valve. I will than pilot all four with one more 3/4" QEV. Would this be effective?

EDIT: I'm not pulling any legs, I'm just as surprised as you guys. I ordered 1 of these valves a week ago, and it came yesterday. Strangely, another 10 came today crammed into one tiny box!

How are you going to connect them to the barrel? The area may be the same but the flow won't be nearly as good as one port.

To connect them to the barrel, I will use 2 tees that have 2 3/4" ports with 1 1.5" port, and than a 1.5" tee.

I will actually have to do that twice if I want to have a single chamber...

Ok but then there is dead space and a lot of turbulence in flow through those tees.

But I allready have a 3/4" QEV cannon with a 3/4" barrel... What else could I do with a single QEV? It would be pointless to waste that size on a smaller barrel, and it would lose performace to give it a bigger barrel. Nope, I'm gonna make a Quad or Hex QEV cannon (should be a first). It might take a while, but I will post it in the showcase when it's done.

Yep, the hard part will be to eliminate as many bottle necks as possible, while keeping dead space to a minimum. Lots of reducing tees and such.

Make a chamber side filling QEV semi, Use a QEV to pilot a large valve, Make a 3-barreled 3 Valved QEV gun, Make a full-auto QEV+pop-off, make a semi auto QEV+DCV, make a piston QEV hybrid. and send the excess to me :lol:
