Safety Instructions
This operation manual must be brought to the attention of the operating personnel.
6.1
General Notes on Safety
The safety instructions for valves also apply to the pipeline systems, into which they are
installed. This operating manual exclusively focuses on safety instructions, which are to
be additionally complied with for valves.
6.2
Safety Instructions for Operators
!
Danger
to Life
A valve with a permissive pressure/temperature range that is not sufficient
for the operating conditions may not be operated! This range is to be derived
from the P/T diagram. With regard to materials, pressures or temperatures
not listed there, contacting the manufacturer is mandatory.
Ignoring this regulation can result in life-threatening situations and can
cause damage to the pipeline system.
!
Danger
to Life
It must be ensured that materials selected for the parts coming into contact
with the media are suitable for the utilized media. The manufacturer takes
no responsibility for damages resulting from corrosion or through aggressive
media.
Ignoring this regulation can result in life-threatening situations and can
cause damage to the pipeline system.
The following items do not lie in the scope of responsibility of the manufacturer. As a
consequence, when utilizing the valve, it must be ensured that
»
the valve is only utilized in accordance with its proper use, as illustrated under
"Proper Use".
»
the actuator unit, which is subsequently mounted on the valve, is adjusted to the
valve and correctly adjusted in the end position.
»
when connecting a valve actuator to the power grid, the safety notices of the
actuator manufacturer are complied with.
»
the valves are correctly implemented into the system, especially those connected
to the pipeline system by means of welding.
»
no additional tensions bear on the valves.
»
the operation parameters and operating conditions have been clarified with the
manufacturer of the valve and that operating conditions such as vibrations, water
hammers, pressure surges, erosion etc. are to be avoided.
»
pipeline system connections and valves, which are operated at operating
temperatures > 50 °C or < -20 °C, are protected against contact.
»
during welding procedures, the safety regulations of the plant operator and/or
plant constructor are to be complied with.
»
the valve is only operated and maintained by trained personnel.
»
valves, which are utilized with hazardous media (inflammable, corrosive, harmful
to health etc.), are to be handled in accordance with their dangers. The
corresponding handling regulations are the responsibility of the plant operator.
»
all ergonomic hazards are to be considered by the plant operator, such as e.g.
accessibility, gauges etc.
