Got a full rate/section control setup on our sprayer, with a standard valve controlling the hydraulic flow to the pump. It all works very well most of the time, adjusts and holds a rate going through the field fine. However randomly the pump doesn’t slow down when I get to the end of the field and all the valves shut off so the pressure pegs out. I currently have it set to standard valve and at least half the time it behaves as expected and spools the pump down when everything closes. For this setup is the standard valve the setting to have or should I be running it as a combo valve? Only difference as far as I can tell is that it closes the valve when the sections turn off, which I believe should solve my problem. Or is there another setting I’m missing somewhere?
A standard valve shouldn’t change when when spraying is stopped. Just the sections valves should shut off. A combo valve will close when spraying is stopped. The only other possible setting that might help is a high enough minimum power to make the valve move.
Ok, so in this situation the combo valve the way to go then? I believe I have the min power at 45, seemed like that was the lowest it could be and move yet.
Should the pump be turned off when the sections are off? The combo valve will do this.
Not necessarily turned all the way off but slowed down significantly. My concern with shutting it off completely is it taking longer to get locked back on the rate. I plan on trying the combo though to see how it acts once I can get back to it. I’m going to put a pressure bypass in as well as a safety as well.
