5. Operating instructions
Air bleeding of hydraulic system
During initial startup, after an oil change as well as
after the opening of lines or valves the hydraulic
system must be air bleeded.
Filter
The function and lifetime of the valve are strongly
a󰀨ected by the cleanliness of the uid.
Purity level class of 18/16/13 acc. ISO4406 is
required.
Pay attention to maintenance details!
Flushing
It is recommended to ush the pipelines by short
circuiting the pressure and return lines. This pre-
vents the installation dirt from entering the valve.
6. Maintenance
Maintenance procedures may only be car-
ried out by specialist personnel. A detailed
knowledge is required of how the machine
is switched on and o󰀨 and also of the ne-
cessary safety measures.
Regular maintenance is essential in prolonging the
service life of the systems, and safeguards plant
safety and operational availability. The following
items must be checked at regular and short intervals:
• Oil level in tank
• Max. medium temperature
• Max. surface temperature
• Condition of the pressure uid (sight check,
colour and smell of hydraulic uid)
• Operating pressures
• Preload pressure of pressure vessel (if pre-
sent)
• No leaks at any system components
• Condition of the lter elements
• Condition of the hose lines
• Cleanliness of components
After a certain period of service, the hydraulic uid
must be replaced. The frequency of the change
depends on the following circumstances:
• Type and grade of pressure uid (ageing)
• Filtration
• Operating temperature and ambient condi-
tions
Replacement of a coil
In case of a necessary replacement of a coil the
disassembly and assembly instructions on dra-
wing 35015707 (see next page) have to be ob-
served. Before exchanging a coil the name plates
of old and new coil have to be checked. It must
be ensured that only coils with identical voltages
are used.
Available coil kits are:
AK-D1VWCJEE93 24 V DC
AK-D1VWCPEE93 110 V / 50 Hz
AK-D1VWCNEE93 230 V / 50 Hz
The coils of series 93 are suitable for valves of
series 91 as well as 92 and 93.
