General Description
These new solenoid operated poppet
valves are used mainly for starting,
stopping and controlling the direction of
linear and rotary actuators or for use as
a pilot valve. The gasket mounted types
can also be used for controlling the pilot
functions of cartridge valves to ISO 7368
(DIN 24342) (see catalog 2378).
All valves are of a “zero leakage design”
which is the major design feature of
poppet-type valves. The valves are
available as either gasket mounted or
cartridge insert type. The latter requires
a housing having a purpose-formed
recess (see recess hole drawing and
special tool note).
Advantages
F Zero internal leakage in closed
position
F Fast consistent response times
F Cost-efficient high pressure capability
F Simple assembly and installation
F Fast and easy servicing

Response Times
Time taken from when signal is first
applied at solenoid until armature
completes its travel. Based on average
conditions with warm solenoids at 95%
rated voltage:
AC and DC energizing 150 ms. . . . . . .
AC and DC* de-energizing 85 ms. . . . . .
*
In pure switched circuit conditions devoid
of the effects of any suppression diodes
and full-wave rectifiers.
Hydraulic Fluids
All valves can be used with anti-wear
hydraulic oils, water-in-oil emulsions and
water glycols. Add prefix “F3” to model
designation when phosphate ester (not
alkyl-based) or chlorinated
hydrocarbons are to be used.
The valves are also suitable for use with
high water-based fluids (95% water, 5%
oil) up to 200 bar.
The extreme operating viscosity range is
from 300 to 13 cSt (1460 to 70 SUS) but
the recommended running range is 54 to
13 cSt (250 to 70 SUS).
For further information about fluids see
catalog 920.

* To obtain optimum service life from both
fluid and hydraulic system, 65_C (150_F)
normally is the maximum temperature
except for water-containing fluids.
For synthetic fluids consult manufacturer
and your Vickers representative where
limits are outside those for petroleum oil.
Whatever the actual temperature range,
ensure that viscosities stay within the
limits specified in the “Hydraulic Fluids”
section.
Contamination Control Requirements
Recommendations on contamination
control methods and the selection of
products to control fluid condition are
included in Vickers publication 9132 or
561, “Vickers Guide to Systemic
Contamination Control”. The book also
includes information on the Vickers
concept of “ProActive Maintenance”.
The following recommendations are
based on ISO cleanliness levels at
2 mm, 5 mm and 15 mm. For products in
this catalog the recommended levels
are:
Up to 210 bar (3050 psi) 20/18/15. . . . .
Above 210 bar (3050 psi) 19/17/14. . . .
