Hydraulic valve technology

Here's another Flint Hydraulics Tech Tip: Like most technologies, hydraulic valve technology has advanced far beyond what it was 45 years ago when automated grading was in its infancy. Modern valve systems incorporate capabilities that not only simplify the installation of an add-on valve system, they make it possible for the contractor to take full advantage of the capabilities of advanced control systems without compromising the integrity of his machine's hydraulic system.

Directional control valves - then and now

Here's another Flint Hydraulics Tech Tip: In the early days of automated grading, the only practical valve solutions were "industrial valves," those used in factories - not on mobile equipment. When these valves were used to automate earth-moving machines, additional valves had to be installed, resulting in a mass of valves, hoses, adapters, tubes, etc. All this forced into the confined space of a mobile machine was unsightly. Not so today!
