| One alternative would be to have two orifices of the same size (if you are talking about double the flow). The second one could have an air-on style module, so that you are literally just having a switch to turn on the air to open the orifice. That way you can still stack keep your sections plumbed the same way with less costly way of opening an air line than having electronics going to each row.
Keep in mind there are shut-off modules for sprayer/liquid kit parts that are air-on (so they need air to turn on), or air-off (that act as a diaphragm check valve, but can have air applied to them to force them closed - usually around the 20PSI above application pressure)
Might be an option. At the very least, if you are pretty aware of your speed changes, you could just have a little sectional air controller so you'd have your few buttons in the cab if you were wanting to keep it by section still (depending on how your sectional plumbing is set up) | |
