6.2 Storing the hydraulic valve

Hydraulic valves are delivered in an unobjectionable state.
For transportation and storage of the product, always observe the environmental
conditions specified in "Data sheet 24751-XE". Improper storage may damage
the valve.
Hydraulic valves can be stored for up to 12 months under the following conditions:
Ensure a storage temperature range of +5...+40 °C.
The relative air humidity may not exceed 65 %.
The storage rooms must provide 100 % UV protection.
No ozone formation may occur near the storage facility.
The storage facilities must be free from etching substances and gasses.
Do not store the valve outdoors but in a well-ventilated room.
Protect the valve against humidity, particularly ground humidity. Store the valve
on a shelf or on a pallet.
Store the valve protected against impacts and sliding and do not stack it.
Store the valve in the original packaging or comparable packaging in order to
protect it from dust and dirt.
All connections at the hydraulic valve must be closed with closing elements.
After opening the transport packaging, it must be closed properly again for
storage. Use the original packaging for storage.
Check the complete valve for damage and corrosion prior to installation.
In a test run, check the valve for correct function and leak-tightness.
After expiry of the maximum storage time, we recommend having the valve
checked by your competent Rexroth service. In case of questions regarding
spare parts, please contact the Rexroth service responsible for your valve,
see chapter 10.6 "Spare parts".
If a dismounted valve is to be stored, it has to be preserved for the time of storage to
protect it against corrosion.
Rexroth recommends the following procedure:
Clean the valve, see chapter 10.1 "Cleaning and care".
Close all connections air-tightly.
Moisten the unpainted external metal surfaces of the valve using an appropriate
corrosion protection agent.
Pack the valve with a desiccant air-tightly in corrosion protection film.
Store the valve protected against impacts.
In each case, please observe any applicable provisions and laws regarding the
handling of substances hazardous to water or to health.
