Wear, tear and malfunctions!
The cleanliness of the hydraulic fluid has a considerable impact on the cleanliness
and life cycle of the safety valve. Any contamination of the hydraulic fluid will result
in wear and malfunctions. Particularly foreign particles may damage the safety
valve.
Always ensure absolute cleanliness.
f
Install the safety valve free from any pollution.
f
Make sure that all connections, hydraulic lines and attachment parts are clean.
f
When sealing the connections, make sure that no contamination can get into the
f
system.
Ensure that no cleaning agents are able to penetrate the hydraulic system.
f
Have sufficiently dimensioned collecting containers, non-linting cloth and medium-
binding materials ready in order to collect or bind leaking hydraulic fluid.
Check the scope of delivery for completeness and transport damage.
f
Compare the material number and the designation (type code) with the details
f
in the order confirmation. If the material number of the safety valve does not
match the number in the order confirmation, contact the Rexroth service for
clarification; for the address see chapter 14.2 "List of addresses".
Check whether the information in the setting certificate and in the declaration of
f
conformity correspond to the data indicated at the safety valve and whether they
comply with the requirements of the system.
Check whether the response pressure indicated at the safety valve (last number
f
of the component marking) and the maximum flow (second to last number of the
component marking), if indicated, comply with the requirements of the system.
The value for the maximum admissible flow which is specified for the relevant
f
safety valve in the technical data must always be higher than the maximum
possible flow of the system at the selected response pressure. See also
"Data sheet 25802".
