Modern valve versatility

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.

Danfoss Proportional Valve Groups

PVG stands for Proportional Valve Group, and the PVG series is certainly the highest quality and most adaptable mobile hydraulic directional control valve on the market. However, PVG valves are not limited to configurations as electro-hydraulic proportional valves. Other configurations include on/off solenoids, hydraulic pilot operators, pneumatic operators and manual handles. And most of these actuators can be mixed with one valve stack.
