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:
Stable air humidity 60 % and
12 months stable temperature >5 °C - <25
°C
Fluctuating air humidity and
6 months fluctuating 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 hydraulic diagram
must contain the design pressure settings for all
pressure valves.
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.

Pilot Operated Pressure Relief Valves
Series R4V*/R6V*/DSDU*
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 specified by the manu-
facturer for installing the product (see "Technical
data", section 16.).
Use the correct tool for installing the fastening bolts.
Install the fastening bolts to the torques
specified by the manufacturer (see "Tech-
nical data", section 16). Tighten the bolts
diagonally.
The factory setting for the maximum
pressure must not be changed – "safety
function".
If the lead seal for the pressure setting
is damaged, the product must not be
used until the product-specific pressure
setting has been restored and sealed by
an accredited inspector to prevent the
setting being changed.
Subplate mounted valves must only be
installed as indicated in ISO 6264.
Before commissioning, the specialist
personnel must verify that the entire
hydraulic system has been installed
correctly.
Commissioning must be carried out with
care, taking account of all safety regula-
tions.
