2. Safety instructions
Read the operating instructions thoroughly before
installation, commissioning, maintenance, repair and
storage, and observe them. Failure to observe the
operating instructions may result in damage to the
valve or the parts of the system connected to it.
In particular, in the case of explosive atmospheres,
any failure to observe the operating instructions
may result in an explosion.
The system operator must make these operating
instructions visible and easily accessible to opera-
ting and maintenance personnel.
Compliance with applicable standards/legal requi-
rements must be enforced. This particularly applies
to plant safety and environmental protection.
A list of such standards, etc. appears in the annex
by way of example.
Before starting commissioning, installation, main-
tenance and repair work, the hydraulic system must
be depressurised and power must be disconnected
from the electrical installation.
In addition, the electrical installation must be secured
so that power cannot be restored unexpectedly.
The valve may become hot during operation. To
avoid risk of burns, do not touch the valve surface.
The system operator must monitor the temperature
and cool the oil if necessary in order to the keep
within the maximum temperatures set out in these
operating instructions (see technical data). In this
connection, observe the relevant directions in the
operating instructions of the supplier (solenoid
system).
Any leaks occurring at the valve must be rectified
immediately.

4. Installation
Scope of delivery
As soon as you receive the valve you should
check if the package has the specified contents.
In particular, check whether the type of protection
indicated on the valve is as described in these
operating instructions.
The scope of delivery includes:
• Valve
• Operating instructions (including operating in-
structions of the valve as well as of the soleno-
id and the declarations of conformity of the
manufactures)
As soon as you receive the shipment, please
check for any obvious signs of damage
caused by careless transport. Document the
transport damage and immediately notify the
carrier, the insurance company and the
supplier.
Installation
• Compare the valve type as stated on the Name
plate with the parts list/circuit diagram.
• The valve can be installed in any position, eit-
her fixed or movable.
Check the fixing surface and the cavity for
the valve.Permitted values: unevenness 0.01
mm/100 mm, roughness Rmax = 6.3 μm.
Keep the valve mounting surface and the
area clean.
• Before installation, remove the protective co-
ver from the valve ports.
• Check that the valve ports and the O-rings are
in the correct position.
• Use fastening screws as indicated in the cata-
logue, property class 12.9 to ISO 4762.
Parker can supply the correct screw sets,
see the catalogue for order numbers.
• Tighten the screws diagonally, torque as speci-
fied in the catalogue.
• Any deficiencies of the valve mounting surface
may result in operating disruptions. Faulty fi-
xing and incorrect screw tightening torques
may lead to the sudden escape of hydraulic
fluid at the ports.
The valve must be connected to the equipotential
bonding system of the hydraulic system.
Electrical connection
Observe operating instruction D14-2114PD-* in
the annex.
Operation limits
The valve may only be deployed with the specified
limits of use. The relevant details can be found in
the catalogue sheet under "Technical data" and
"Characteristic curves".
Observe the ambient conditions. Unauthori-
sed temperatures, shocks, the effects of
aggressive chemicals, radiation, unauthori-
sed electromagnetic emissions may result
in disruptions and failures.Observe the limits
of operation set out in "Technical data".
Excessive temperatures may cause the
solenoid to overheat, creating the risk of
explosion.To permit adequate heat dissipa-
tion, the solenoid coil should not be painted.

5. Operating instructions
Electronic control system
The valve must be operated by a suitable electronic
control system.
The appropriate electronic control system
can be selected from the catalogue ("Elec-
tronics" section). Please ask the factory. if
further guidance is required. Connecting to
an unsuitable electronic control system may
result in irreparable damage to the valve or
the electronic control system.
If you are using the Parker PCD00A-400
digital module, make sure that the module
runs outside the Ex area or inside an electri-
cal cabinet certified for use in the Ex zone.
Air bleeding of hydraulic system
During initial startup, after an oil change as well as
after the opening of lines or valves the hydraulic
system must be air bleeded.
Filter
The function and lifetime of the valve are strongly
affected by the cleanliness of the fluid.
Purity level class of 18/16/13 acc. ISO4406 is
required.
Pay attention to maintenance details!
Flushing
It is recommended to flush the pipelines by short
circuiting the pressure and return lines.This prevents
the installation dirt from entering the valve.
6. Maintenance
Maintenance procedures may only be carried
out by specialist personnel.A detailed know-
ledge is required of how the machine is
switched on and off and also of the neces-
sary safety measures.
Regular maintenance is essential in prolonging
the service life of the systems, and safeguards
plant safety and operational availability. The fol-
lowing items must be checked at regular and short
intervals:
• Oil level in tank
• Max. medium temperature
• Max. surface temperature
• Condition of the pressure fluid (sight check,
colour and smell of hydraulic fluid)
• Operating pressures
• Preload pressure of pressure vessel (if present)
• No leaks at any system components
• Condition of the filter elements
• Condition of the hose lines
• Cleanliness of components
After a certain period of service, the hydraulic fluid
must be replaced. The frequency of the change
depends on the following circumstances:
• Type and grade of pressure fluid (ageing)
• Filtration
• Operating temperature and ambient conditions
Replacement of a coil
In case of a necessary replacement of a coil the
disassembly and assembly instructions on drawing
35015707 (see next page) have to be observed.
Before exchanging a coil the name plates of old and
new coil have to be checked. It must be ensured
that only coils with identical voltages are used.
Available coil kits are:
