6.2 Proportional Valve Settings
Spraying systems that use a proportional valve are controlling a hydraulic valve, which in turn
drives a hydraulic motor which drives a pump. Spray regulation is controlled by changing the
pump speed. The settings will need to be tuned for the sprayer.
Select ‘Prop. Valve’ in the ‘Controller’ window.
Select ‘Settings’, this will then open up the window to allow the operator to alter the settings
for the proportional valve for the tank selected.
