5 Assembly, operation and maintenance recommendations

5.1 Intended use

This valve is exclusively intended for hydraulic applications (uid engineering).

The valve demands high technical safety standards and regulations for uid engineering.

The user must observe the safety measures and warnings in this documentation.

Essential requirements for the product to function correctly and safely:

– All information in this documentation must be observed. This applies in particular to all safety measures and warnings.– The product must only be assembled and put into operation by qualied personnel.– The product must only be operated within the specied technical parameters. The technical parameters are described in detail in this

documentation.– The operating and maintenance manual of the specic complete system must also always be observed.

If the product can no longer be operated safely:

➯ Remove the product from operation and mark it accordingly. It is then not permitted to continue using or operating the product.

5.2 Assembly information

The product must only be installed in the complete system with standard and compliant connection components (screw ttings, hoses,pipes, etc.).

The hydraulic power pack must be shut down correctly prior to dismounting; this applies in particular to power packs with hydraulicaccumulators.

DangerRisk to life caused by sudden movement of the hydraulic drives when dismantled incorrectly!Risk of serious injury or death.

■ Depressurise the hydraulic system.■ Perform safety measures in preparation for maintenance.


5.2.1 Installing the valve

Safety valves must be installed with particular care. The provisions of the Pressure Equipment Directive must be observed. Regularinspections are governed by the national regulations on safety valves and systems. The ow direction must always be respected.

In order to protect against external damage, the valve must be installed in a safe position or a suitable protective device must be tted.

Connect the return line (R) to the tank. The necessary lines must be sufficiently dimensioned. For the housing screw connections of typeMVX, MVSX and SVX, the specied torques must never be exceeded.

NoteCounterhold the piping when tightening the screws.

Tighten the fastening screws of the manifold mounting valve type MVPX and the screw-in valves type MVEX only to the required torques.

Use only width across ats SW1 to tighten type MVEX in the mounting hole of the connecting element.

NoteDo not damage the sealing wire!

5.3 Operating instructions

Product configuration and setting the pressure and ow rate

The statements and technical parameters in this documentation must be strictly observed.The instructions for the complete technical system must also always be followed.

Note■ Read the documentation carefully before usage.■ The documentation must be accessible to the operating and maintenance staff at all times.■ Keep documentation up to date after every addition or update.

CautionRisk of injury on overloading components due to incorrect pressure settings!Risk of minor injury.

■ Always monitor the pressure gauge when setting and changing the pressure.

Purity and ltering of the hydraulic uid

Fine contamination can significantly impair the function of the hydraulic component. Contamination can cause irreparable damage.

Examples of ne contamination include:

– Metal chips– Rubber particles from hoses and seals– Dirt due to assembly and maintenance– Mechanical debris– Chemical ageing of the hydraulic uid

NoteFresh hydraulic uid from the drum does not always have the highest degree of purity. Under some circumstances the freshhydraulic uid must be ltered before use.

Adhere to the cleanliness level of the hydraulic uid in order to maintain faultless operation.(Also see cleanliness level in Chapter 3, "Parameters").

5.4 Maintenance information

This product is largely maintenance-free.

Conduct a visual inspection at regular intervals, but at least once per year, to check if the hydraulic connections are damaged. Ifexternal leakages are found, shut down and repair the system.

Clean the device surface of dust deposits and dirt at regular intervals, but at least once per year.
