Here's another
Flint Hydraulics Tech Tip: As an example of modern valve versatility, one application involves proportional solenoids on two sections of a three section valve and an on/off solenoid on the third section. This is useful on a motor grader if the GPS control system offers automated side shift capability. The two proportional valve sections control blade elevation with variable speed capability, while the on/off section controls the less frequently used side-shift function at a preset flow rate. And all three can operate simultaneously.
