7. Storage
If the product needs to be temporarily stored, it
must be protected from dirt, the weather, and dam-
age. Each valve is tested with hydraulic oil in the
factory, so that the internal components are pro-
tected from corrosion. However, this protection can
only be guaranteed under the following conditions:
Storage time: Conditions:
12 months
Stable air humidity 60 %
and stable temperature
>5 °C - <25 °C
6 months
Fluctuating air humidity and
uctuating temperature
>5 °C - <35 °C
The product is delivered with adequate corrosion
protection, provided our recommendations for the
ambient conditions are followed.
Storage outside or in maritime or tropical
climates without appropriate packaging
leads to corrosion and may make the
product unusable.
Make sure the product is stored so that
no injuries can be caused by tipping or
falling. In particular, make sure that the
safety rules for high-bay racking are
followed.
8. Commissioning
After installing our product in a system/machine,
make sure that the requirements of the Machinery
Directive are met if applicable.
Access should be provided to the hydraulic dia-
gram, the equipment list and the logic diagram for
the system/machine.
The product must be checked for dam-
age and missing parts (e.g. seals) before
installation, especially in the area of the
sealing surfaces and the safety devices.
If the safety devices or sealing surfaces
are damaged or are missing individual
parts with relevance to the product's
function, the product may not be used.
Remove all transport securing devices, protective
covers and packaging.
Check for foreign objects in the open
hydraulic passages. Contaminations
may impair operational reliability and
shorten the service life.
Make sure that the hydraulic system/
machine is unpressurised before the
product is installed.
Use the nameplate to compare the valve type with
the bill of materials/diagrams.
Take care during installation, to guarantee that
all requirements for the safe use of the product
are met.
Ensure that the sealing rings are seated correctly.
Only use the fastening bolts specied by the manu-
facturer for installing the product (see "Technical
data", section 16.). The user should check again if
additional components are added to the valve (e.g.
sandwich plates)
Use the correct tool for installing the fastening
bolts.
Install the fastening bolts to the torques
specified by the manufacturer (see
"Technical data", section 16.). Tighten
the bolts diagonally.
If the seal of the position control system
is damaged, there is a risk that the valve
will not work properly. In this case, the
valve must be returned to the manufac-
turer.
The DCV valves must only be installed
as indicated in ISO 4401.
