4.2
Working at valves
•
Working at valves has only to be carried out in unpressurized and cooled condition. The evapora-
tion temperature of the medium must fall below in every space coming into touch with the
medium.
•
Working at valves with actuator has only to be carried out in standstill condition. The procedure
described in the operating instruction regarding the shut down, must absolutely be kept. Valves,
coming in touch with media which are detrimental to health must be decontaminated.
•
All safety- and protective devices must be installed or taken to function immediately after the work
has been finished.
4.3
Staff
Technically trained staff is the prerequisite for operating the valves. KLINGER SCHÖNEBERG ball valves
are manufactured according to the current state of the art and operationally reliable. However, if they are
operated or not proper installed by untrained staff it can be dangerous, as the valves are comparable with
pressure vessels. The following points must be taken into consideration:
•
The staff must be technically trained.
•
The operator must assure that the content of the operating instructions is fully understood by
the staff.
•
The staff for operation, inspection and assembly must be aware of the mutual reaction between
valve and plant.
•
Operating error of a valve can lead to emphatic consequences e.g.:
o
outflow of the medium
o
machine/plant down time
o
impairment (decrease/increase of the effect/function) of the plant/machine
o
fail of important functions of the valve/plant
o
fail of specified methods for maintenance
o
endangering of persons because of thermal, electric, mechanical and chemical
influences
o
endangering of the environment due to leakage of dangerous substances
Due to the wrong handling, leaving media can lead to injury to persons, to damage and altera-
tion of the environment. Therefore, beside this operating instruction, relevant regulations of
rules for prevention of accidents and technical rules must be taken into consideration.
4.4
Notes for the operator
•
If hot or cold parts of the valve (e.g. parts of the body or hand lever) are a danger for the user,
these parts must be safeguarded by customers against touch from the operator.
•
Leakages (e.g. of the stem packing) of dangerous material to be conveyed (explosive, poisonous,
hot), must be drained in that way that no endangering arises for persons and environment. Legal
regulations have to be kept.
•
Endangering due to electrical energy is to be excluded (details can be taken e.g. from the regula-
tion of the VDE and the local electric supply company).
The KLINGER SCHÖNEBERG company will not take any responsibility for damage or plant
disturb arising from the improper handling or non-compliance of this operating instruction and
for amendments carried out without the agreement of the manufacturer.
