Subject: nh3 shutoff valve for 2 rows


SE NE
I have an aNH3 system and would like to shut the outside rows off (#1 and #13) and lift the row units up (they lift hydraulically). If I stop the flow to the 2 rows I'm pretty sure the aNH3 system will continue to distribute the NH3 evenly -- the question is, what can I use to shut the NH3 off? Obviously I can use normal 1" on/off valves, but was hoping for something smaller/cheaper. Adding 2 - 1" valves at $450 a piece seems to be a bit overkill but maybe that is my only option.

FYI - the reason I want to shut the outside rows off is because I am applying NH3 between the existing rows and want to keep the same wheel tracks as my 12 row planter. I can either split the NH3 in 1/2 for the outside rows ( the typical way it is done), or apply 13 in 1 direction and 11 the other direction. I figure the horsepower savings in raising the outside units up is worth the cost of the valves required to shut the NH3 off.
