The check is to be carried out as well if the valve is only stored but not used!
For order details of seal kits, refer to chapter 10.6 "Spare parts".
In order to ensure a long life cycle and functionality, include the following activities
in your maintenance schedule for the overall system:
1.
De-energize the connection line.
2.
Remove coarse dirt from the exterior.
CAUTIOn! Damage to property and personal injury caused by electrostatic charging!
▶
In order to prevent electrostatic charging, only clean the coil and the mating
connector using a damp cloth.
3.
Check all external fittings for completeness and tight seat.
4.
Check the connection line and the mating connector for tight seat and damage.
If there is visible damage, replace the connection line and the mating connector.
5.
Check the valve for external leakage; replace the sealing devices, if required,
see chapter 10.5 "Rectifying external leakages".
10.3 Maintenance schedule
Valves are low-maintenance provided that they are used as intended.
To ensure that the valve functions reliably for a long time, Rexroth recommends
checking the hydraulic system and the valve regularly.
10.3.1 Checking for leakage
Check the valve for leakage. Early detection of hydraulic fluid loss may help you
identify and remedy errors. Bosch Rexroth therefore recommends always keeping the
valve and/or the system clean.
10.3.2 Checking for noise development
Check the valve for noise development. Based on noise development or the increase
of noise development, a possible failure of one or several components can be
recognized in time and consequential damage can be avoided.
10.3.3 Checking the mounting elements
Check the mounting elements for tight seat. All mounting elements are to be
checked when the system is switched off, depressurized and has cooled down.
