Viscosity range
recommended viscosity range at 38 °c (100 °f)
maximum permissible viscosity range at 38 °c (100 °f)
recommended cleanliness class according to iso 4406
for functional safety
for longer service life
1) unbiased pilot valve for fail-safe options w
2) Biased pilot valve for fail-safe options d, f, m and u
3) pressure peaks up to 210 bar (3,000 psi) permissible
4) the cleanliness of the hydraulic fluid strongly affects functional safety (e.g. safe positioning of the spool, high resolution) and wear
of lands (e.g. pressure gain, leak losses).
