Near Intersection of I-35 & I-90 Southern Mn. | I believe they will. Most ON/OFF valves cycle very rapidly and should give you almost instant full flow.
We did have a "less than full rate" problem after starting a pass with my present Hagie STS-12 Sprayer. It is controlled by an Ag Leader Liquid Product Control Module. It uses PWM pump control to adjust the rate. My former Hagie used a Servo hydraulic arrangement for the pump. When I setup the newer Hagie with the PWM control system, I made an error in the setup.
Due to my error, the pump was being slowed way down when I turned the sections OFF to turn around on the Headlands.. Shutting OFF wasn't the problem but when the system came back ON for the next pass, the pump was running slowly and needed "time" to catch up. If the operator would accelerate slowly when starting a new pass, the system could "catch up" quickly enough to deliver the proper rate. If the operator would mash the Joystick ahead for normal speed, the rate was low at first. It would eventually catch up but by then the sprayer was down the pass a fair distance. The first part of each pass was at less than desired rate. A simple solution would have been to accelerate more deliberately at the start of each new pass. This might have worked for you also but is a bit of a nuisance.
Instead I modified the setup. I was able to change the "what to do when all sections are OFF setting". I set the PWM setting to a level that was close to what the system was using at a normal speed and rate. This meant that the pump was turning at about the needed rate while turning around. Some flow was desirable anyway for agitation. Then when application resumed, the pump was running at about the usual speed and the application rate was close to being correct right away. After that the system behaved as usual and changed the pump speed as needed for variations in ground speed etc.
This probably doesn't apply to your system since your system is using a butterfly in the product line and your pump is likely running at a constant speed based on engine speed. I mention it since sometimes, a problem is linked to the wrong cause. We could have concluded that the section valves on our Hagie were opening too slow and thus causing the low rate at first. Instead the problem was reduced flow at first.

Which raven boom valves do I have?
