Wear, tear and malfunctions!
The cleanliness of the hydraulic fluid has a considerable impact on the cleanliness
and life cycle of the valve. Any contamination of the hydraulic fluid will result in
wear and malfunctions. Particularly foreign particles may damage the valve.
▶
Always ensure absolute cleanliness.
▶
Install the valve in a clean condition.
▶
Make sure that all connections, hydraulic lines and attachment parts are clean.
▶
Ensure that no cleaning agents are able to penetrate the hydraulic system.
▶
Only use seal kits as listed in chapter 10.6 "Spare parts".
1.
Before any assembly and disassembly work starts, the environment must be
cleaned so that no dirt can get into the oil circuit. Only fiber-free cloth or special
paper may be used for cleaning.
2.
Remove existing preservative agent.
3.
Check the valve contact surface for the required surface quality
(see "Data sheet 23178-XE"). Remove the protective plate from the valve and keep
it safe for returns in case any repairs become necessary later.
4.
Dry the valve connection surface using suitable cleaning materials.
5.
Check the seal rings at the valve connection surface for completeness.
Other sealants are not admissible.
6.
Check whether at the subplate, the pressure connecting line is connected to P
and the return line to T.
Swapping P and T may cause damage at the valve when pressurized.
7.
Place the valve on the contact surface.
Only use valve mounting screws with the thread diameters, screw lengths and
strength properties listed in chapter 10.6 "Spare parts"!
Always fasten the valve with all 4 valve mounting screws, otherwise leak-tightness
is not guaranteed.
