8 Commissioning
WARNING
Explosion hazard caused by spark formation!
During adjustment works, adjustment speeds >1 m/s may cause inadmissible
heating of the valve and generate an ignition spark!
▶
Operation of the adjustment element is only admissible without additional aids
and only manually.
Faulty assembly!
If the valve is not correctly mounted, persons might be injured and the valve
or system could be damaged when commissioning the valve.
▶
Only commission your system after all hydraulic connections and the valve have
been completely and properly mounted according to the specifications.
▶
Look out for defective sealing points and exchange defective seal rings
immediately.
▶
Wear personal protective equipment during the initial commissioning.
Damage to persons and property!
Commissioning of the valve requires basic hydraulic and electrical knowledge.
▶
Only qualified personnel (see section 2.4 "Qualification of personnel")
is authorized to commission the valve.
▶
Make sure that all hydraulic connections are closed.
▶
Commission the valve only if it is completely installed.
▶
Immediately depressurize the system if hydraulic fluid still leaks despite proper
assembly and continue with chapter 14 "Troubleshooting".
To make sure that the maximum admissible pressure for the relevant system is not
exceeded during initial commissioning, the valve must be set to the minimum
adjustable pressure by turning the adjustment device counter-clockwise before
pressurization.
Observe the operating instructions of the device and/or system into which the
valve is installed.
Switch the valve several times under operating pressure before the actual operation.
This will press out any remaining air from the valve. Thus, mechanical damage
being caused by inadmissibly high acceleration of the fluid and the closing element
is avoided and the life cycle of the valve is extended.
Check whether during operation hydraulic fluid leaks at the valve and at the ports.
The released operating media and limitations of operation for your valve are
