Endangerment to service personnel
Explanations
Measures
Squeezing danger to fingers, hands and feet
Unintentional opening and closing of the valve must be prevented
during maintenance work.
Do not place your hands in the valve housing or the seat area of
the valve disk.
The valve weighs several kilograms.
Bruising injuries can arise during transport, assembly or in
maintenance work.
Disconnect the electrical connection to the
valve.
Disconnect the pneumatic connection to
the valve.
(Compressed air hose)
Always wear safety shoes and protective
gloves.
Secure the valve against slipping and falling
during assembly, disassembly and in
maintenance work.
Blow and impact danger
Low spring tension
Before taking out the valve inset and loosening the screws, the
valve can be pneumatically lifted.
When carrying out maintenance work the piping system should be
made pressure-free or drained beforehand in the area concerned.
The piping area awaiting maintenance should be sealed off from
the other piping system.
Apply compressed air to the main drive.
Before removing the valve inset, check
which liquid medium was in the piping. If
necessary, rinse the piping again
beforehand with water.
Check the piping pressure before the valve
inset is removed from the housing.
Danger of burning, scalding and causticization
If the piping system is subjected to higher media temperatures the
surface temperature of the valve housing can also reach this
value.
If the liquid medium is drained from the system, this can lead to
burns, scalding or causticization for the operating and
maintenance personnel.
Detergent can leak from the leakage outlet during CIP cleaning.
Attach warning signs.
Rinse the piping system with cold water
before carrying out maintenance work.
Install collecting tubs or a collecting piping
system for controlled pressure-free
drainage of the CIP media.
Make sure, if during the maintenance work
the CIP is activated, that no-one is standing
in the danger area of the leakage outlet.
