Direction of rotation:
1)
– clockwise → set pressure increase
– anti-clockwise → set pressure decrease
The cleanliness classes specified for the components must be

adhered to in hydraulic systems. Effective filtration prevents faults
and at the same time increases the life cycle of the components.
