2.2 User safety instructions
The operator of the valve must ensure that the valve is only used in accordance with the
intended use. This
is not the responsibility of the manufacturer. The valve may only be operated by properly qualified and
trained staff. The operating manual and the corresponding safety instructions must be read and understood.
It is prohibited to use any valves with a nominal pressure ("PN") and maximum admissible
operating temperature insufficient for the operating conditions.
The approved range is indicated on the valve.
Warning: Temperatures below 10 °C and above 40° C during work on the pipeline parts involve
the risk of injury. Protective measures must be taken accordingly.
Operating media must correspond to the specification of the valve. The manufacturer does not
assume any liability for damage resulting from corrosion caused by aggressive media. Neglect
of these regulations may result in imminent danger to life and health, and may cause damage to
the pipeline.
2.3 Special risks
Be sure to free the pipeline from any pressure and risk prior to disassembly, maintenance and
repair of the valve. During disassembly the medium may leak, therefore the pipeline and the valve
must be completely emptied.
The energy supply must be switched off.
