Maintenance and repair

The following inspection, testing and maintenance works are to be carried out
regularly. The intervals for the same have to be selected in a way - also dependent
on the operating conditions - that deficiencies that have to be anticipated are
identified timely. The check must, however, at least be carried out every
three years
from the date of manufacture of the valve.
The date of manufacture of the valve can
be found on the name plate, see chapter 5.1.1.
Before initial commissioning or re-commissioning of the valve in the system,
check whether the valve requires maintenance. If required, carry out
maintenance.
For order details for seal kits, please 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.
Remove coarse dirt from the exterior.
2.
Check valve for external leakage. Replace the seals, if required, see chapter 10.5
"Rectifying external leakage". For order details regarding the seal kits, refer
to chapter 10.6 "Spare parts".
3.
Check all external fittings for completeness and firm seat.
4.
Check the valve function regarding the application conditions.
10.3 Maintenance schedule
Valves require low maintenance when you use them as intended.
For a long and reliable operation of the valve, Bosch Rexroth recommends
to regularly check the hydraulic system and the valve.
10.3.1 Checking for leakage
Check the valve for leakage. Early detection of hydraulic fluid loss may help you
to identify and remedy errors. Bosch Rexroth therefore recommends that you keep
the valve and/or the system permanently 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 that the mounting elements are attached firmly. All mounting elements are
to be checked with the system being switched off, depressurized and cooled down.
