Hydraulic fluids
The oil for the proportional valves must have a minimum cleanliness level 20/18/15 in accordance with ISO 4406 at a minimum.
Bucher Hydraulics recommends the use of hydraulic fluids with additives for wear protection in mixed friction operation. Hydraulic fluids without additives will reduce the service life of the valves. The user is responsible for maintaining and continuously checking the quality of the hydraulic fluid.
