Other Viscosities
Published pressure drop data is valid for
a fluid viscosity of 21 cSt (102 SUS).
The graph shows the approximate
percentage change in pressure drop for
a range of other viscosities. To
determine the approximate pressure
drop for any given fluid viscosity, multiply
the published data by the % factor for
the required viscosity.

To adjust valve setting, slacken M4 locking
screw and rotate knob . Re-tighten locking screw

Warranty and Repair
Units to be returned under warranty
should be sent, with a description of the
fault, to the Vickers representative in
your area.
Repair of these size 03 valves is not
generally economically viable. Contact
your nearest Vickers representative
before returning any unit for repair.
Ordering Procedure
Specify requirements by valve model
code, and by seal kit number.
