Liability
The manufacturer cannot accept liability for loss or
damage resulting from the following faults:
• incorrect installation
• unqualied operation
• inadequate maintenance
• use beyond specication
Do not dismantle the valve. If you suspect a
defect, return the valve to Parker.
Storage
If the valve needs to be temporarily stored, it must
be protected from dirt, the weather, and mechanical
damage. Each valve is tested with hydraulic oil in the
factory, so that the internal components are protected
from corrosion. However, this protection can only be
guaranteed under the following conditions:
Storage time Storage requirements
12 months constant air humidity < 60 %
constant temperature < 25 °C
6 months varying air humidity,
varying temperature < 35 °C
Storage outside or in maritime or tropical
climates leads to corrosion and may make
the valve unusable.
4. Installation
Scope of delivery
As soon as you receive the valve you should check
if the package has the specied contents. In parti-
cular, check whether the type of protection indica-
ted 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 xed or movable.
Check the xing 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 spe-
cied in the catalogue.
• Any deciencies of the valve mounting surface
may result in operating disruptions. Faulty -
xing and incorrect screw tightening torques
may lead to the sudden escape of hydraulic
uid at the ports.
The valve must be connected to the equipotential
bonding system of the hydraulic system.
