WARNING
Penetrating water and humidity!
In case of use in humid or wet environments, water or humidity may penetrate
at electrical connections. This may cause malfunctions at the valve and unexpected
movements in the hydraulic system, which may result in personal injury and damage
to property.
▶
Only use the valve within the intended IP protection class or lower.
▶
Ensure before the assembly that all seals and caps of the plug-in connections are
tight and intact.
CAUTION
Contaminated hydraulic fluid!
Contamination in the hydraulic fluid may cause functional failures e.g. jamming
or blocking of nozzles of the valve. In the worst case, this may result in unexpected
system movements and thus constitute a risk of injury for persons.
▶
Ensure an adequate hydraulic fluid cleanliness according to the details in the
data sheet over the entire operating range.
Leakage in case of incorrect working temperatures!
Use of the valve outside the approved temperature range may lead to permanent
leakage at the valves. Thus, hydraulic fluid in the form of a leaking hydraulic fluid jet
may injure persons, lead to damage to property and endanger the environment.
▶
Only use the valve within the intended environmental and hydraulic fluid
temperature range.
▶
In case of leakage, immediately exchange damaged seal rings or the valve.
Corrosion!
The valve described has surface protection (see
Data sheet “29115-XE”
). Use of the
valve in humid environments still holds the danger of corrosion on the valve and
on the valve mounting screws and thus a reduction of the preload force of the
screw connection. To prevent the valve from becoming loose and causing a risk
of injury:
▶
Exchange the valves with corrosion damages as soon as possible.
▶
Check the surface protection on the valve and the valve mounting screws
at regular intervals.
Contact with salt water leads to increased corrosion on the valve. This may
chemically corrode and damage individual components of the valve. Therefore
take suitable corrosion protection measures.
