HYDRAULICS – COMPLEXITY

The hydraulic valves for agricultural machinery are designed for use that really pushes the limits. They must withstand enormous forces as well as extreme temperatures and dirt. At the same time, the parts must be very precise in order to guarantee the functioning of the valve.

The demands on the parts are accordingly high: the precision fit requires very tight tolerances and perfect surfaces. The load capacity requires thermal hardening of the parts. Combining the two is very demanding, because the change in dimensions caused by thermal processes must be anticipated during production.
