Intended use

The valve is designed and constructed for the control of
energy and signals using oil flow.
Store the valve only in a dry and dust-free environment
which is free from corrosives and fumes and which is sub-
ject to a low degree of humidity and only minor temperature
changes. For storage exceeding 6 months, we recommend
filling in clean conservation oil.
IMPORTANT
The factory corrosion protection is sufficient if the valve is
stored under the stated conditions and if no condensate or
leakage water may enter the valve.
The valve may only be operated with the hydraulic fluids
stated in the data sheet . Please consult us for information
on the use of the valve with other hydraulic fluids.
The valve may only be operated in a technically perfect con-
dition and used as described in these operating instructions.
The connection conditions, application conditions and per-
formance data defined in these operating instructions must
not be changed.
IMPORTANT
If you intend to use the valve with other connection,
application or performance data than those defined by
Bosch Rexroth AG in these operating instructions, please
contact Bosch Rexroth AG beforehand. The valve must not
be used with other connection, application and performance
data than those defined in these operating instructions with-
out the written approval by Bosch Rexroth AG.
The valve may only be modified in the scope specified in
this part.
Any safeguards fitted by Bosch Rexroth AG have to be pres-
ent, properly installed and fully functional, unless this is not
appropriate for setup or maintenance operation. Their posi-
tion must not be changed, they must not be circumvented or
made ineffective.
Persons under the influence of alcohol, other drugs or phar-
maceuticals that may affect their ability to react must not
operate or maintain Rexroth valves.

tion on the explosion protection or in areas with lower
requirements.
4.5.1 Classification of explosive areas
The user / machine end-user has to classify explosive areas
according to NEC (National Electrial Code) into zones
(class). The following table describes the zones, groups and
temperature classes of Class I (flammable gases, fumes or
vapors) in more detail. During use, also observe the other
information on the explosion protection in the data sheet.
