Minimum-Pilot-Pressure Generator
For valves fitted with this option, the P to
A or B pressure drop derived from the
graph on the previous page is increased
by 3,5 bar (51 psi) at 50 L/min
(13 USgpm).
At any other flow rate Q1 the total
pressure drop becomes:
a. For pressures in bar and flow rates in
Materials and seals used in these valves
are compatible with antiwear hydraulic
oils, water-glycols, water-in-oil
emulsions and non-alkyl-based
phosphate esters. The extreme
operating range is 500 to 13 cSt (2270
to 70 SUS) but the recommended
running range is 54 to 13 cSt (245 to 70
SUS). For further technical information
about fluids see “Technical Information”
leaflet B-920 or I-286S.
Contamination Control Requirements
Recommendations on contamination
control methods and the selection of
products to control fluid condition are
included in Vickers publication 9132 or
To obtain optimum service life from both
fluid and hydraulic system, 65C (150F)
normally is the maximum temperature.
For other fluids where limits are outside
those of petroleum oil, consult fluid
manufacturer or Vickers representative.
Whatever the actual temperature range,
ensure that viscosities stay within those
specified under “Hydraulic Fluids”.
