Assembling the valve

Have sufficiently dimensioned collection containers, enough clean-
ing cloths and medium-binding materials ready in order to collect or bind
leaking medium.
Risk of personal injury and damage to property!
Incorrectly assembled valves can cause substantial material damage and per-
sonal injuries. An improperly attached valve may move in an uncontrolled manner
and damage other system components and also cause errors in the hydraulic cir-
cuit or may lose oil and pollute the environment.
Before any work such as assembly or disassembly is carried out at the valve,
the hydraulic system must be depressurized and the electrical control system
de-energized.
Assembly of the valve requires basic mechanical, hydraulic, pneumatic and
electrical knowledge. Only qualified personnel (see section "2.3 Qualification
of personnel" on page 7) are authorized to assemble the valve.
Ensure that the valve is attached securely.
Wear, tear and malfunctions!
The cleanliness of the hydraulic fluid has a considerable impact on the
cleanliness and service life of the hydraulic system as a whole. Any pollution/con-
tamination of the hydraulic fluid will result in wear and malfunctions. Particularly
foreign bodies like e.g. welding beads or metal cuttings in the hydraulic lines may
damage the valve.
Always ensure absolute cleanliness.
Assemble the valve free from any pollution.
Make sure that all connections, hydraulic lines and attachment parts
(e.g. measuring devices) are clean.
Ensure that also when sealing the connections, no contaminations are able
to penetrate.
Ensure that no cleaning agents are able to penetrate the hydraulic system.
Do not use cotton waste or linting cloths for cleaning.
Do not under any circumstances use hemp as a sealant.
Installing the valve in the system
Risk due to the use of an improper valve
Installing an improper valve may result in uncontrolled activities and in personal
injuries or damage to other system components.
Check based on the type designation on the name plate of the valve whether
there is the correct valve type.
Check the scope of delivery for completeness, particularly the seal rings at the
valve connection surfaces.
Check the scope of delivery for possible transport damage.
Check whether the operating instructions are suitable for the valve.
Please observe all safety instructions.
