3 Safety advice
Depending on the technical circumstances and the time under and at which the valve is mounted,
adjusted and commissioned, you must in each case take into account particular safety aspects!
If, for example, the valve works in an operational chemical plant, the potential hazards of commis-
sioning have another dimension from that when this is only being carried out for test purposes an
a „dry“ part of the plant in the assembly room.
Since we do not know the circumstances at the time of the mounting/adjustment/commissioning,
you may find advice on hazards in the following descriptions which are not relevant to you .
Please observe (only) the advice which applies to your situation!
3.1. Personal protection
3.1.1. Safety advice for mounting
We wish to point out expressly that the mounting, the electrical installation and the adjustment
of the valves and the accessories must be carried out only by trained specialist personnel having
mechanical and electrical knowledge!
Switch off all the devices / machines / plant affected by mounting or repair.
If appropriate, isolate the devices / machines / plant from the mains.
Check (for example in chemical plants) whether the switching off of devices / machines / plant
will cause potential danger.
If appropriate, in the event of a fault in the valve (in a plant which is in operation) inform the
shift forman / safety engineer or the works manager without delay about the fault, in order, for
example, to avoid an outflow / overflow of chemicals or the discharge of gases in good time by
means of suitable measures!
Before mounting or repair, remove the pressure from pneumatic / hydraulic devices / machines
/ plant.
Emty the conduit from medium.
If necessary, set up warning signs in order to prevent the inadvertent starting up of the devices /
machines / plant.
Observe the respective relevant professional safety and accident prevention regulations when
carrying out the mounting / repair work.
Check the correct functioning of the safety equipment (for example the emergency push off but-
tons/ safety valves, etc)!
