3 Safety advice
Depending on the technical circumstances and the time under and at which the armatures and
valves are mounted, adjusted and commissioned, you must take into account particular safety
aspects in each case!
If, for example, a pneumatic actuator works a slide in an operational chemical plant, the potential
hazards of commissioning 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 advices on hazards in the following descriptions which are not relevant to you.
Please observe (only) the advices which applies to your situation!
3.1 Personal advice
3.1.1 Safety advices for mounting
We wish to point out expressly that the mounting, adjusting and at accessories the pneumatically
and electrical installation of the armatures and valves must be carried out by trained specialist
personnel having mechanical, pneumatically and electrical knowledge!
Secure that the machine / plant come up to the Machinery Directive after the mounting and
installing of the armatures and valves.
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 armature / valve (in a plant which is in operation)
inform the shift foreman / 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 repairing, remove the pressure from pneumatic / hydraulic devices / machines
/ plant.
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)!
Safety advice

3.1.2 Safety advice for adjustment / starting
As a result of the starting (pneumatic, electric or by hand) of the armatures and valves the flow
of gases, steam, liquids, etc. may be enabled or interrupted! Satisfy yourself that, as a result of
the starting or the test adjustment no potential hazards will be produced for the personnel or the
environment!
If necessary, set up warning signs in order to prevent the inadvertent starting up or shutting down
of the device / machine / plant.!
By ending the adjustment check the correct function of the armature.
Check the right function of all safety devices (for example emergency push off buttons / safety
valves)!
Carry out the starting and the adjustments only in accordance with the instructions described in
this documentation!
3.1.3 Safety advice for maintaining / repairing
Do not carry out any maintenances / repairs if the armature will be under pressure.
Before disassembling or a armature or valve some essential points should be clarified!
• Will the armature/valve to be disassembled be replaced by another immediately?
• If appropriate, does the production process of the plant needed to be stopped?
• Is it necessary to inform specific personnel about the disassembly?
If necessary, inform the shift foreman/ safety engineer or the manager about the maintenance
or repair without delay in order, for example, to avoid an outflow/ overflow of chemicals or a
discharge of gases in good time by means of suitable measures!
Observe that some valves / armatures are able to enclose the pressured medium e.g. the ball
in the ball valve. You have to relieve the pressure in the pipes in which the armature/valve is
mounted.
Switch off pilot pressure and the power supply and relieve the pressure in the pipes.
If necessary, set up warning signs in order to prevent the inadvertent starting up or shutting down
of the device / machine / plant.!
In case of defect in the armature/valve make contact to the supplier. The telephone number will
be found on the back cover of these mounting and installation manual.
If you ascertain a damage of the armature/valve, isolate the device from the mains. Please
observe the safety advices.
Do not mount, start or adjust the armature/valve if itself, the pipes or a mounted actuator will be
damaged.
After the maintenance or repair check the right function of the armature/valve and the tightness
of the pipe connections.

3.2 Device safety
The armatures/valves
• are quality products which are produced in accordance to the recognized industrial
regulations.
• left the manufacturer`s work in a perfect safety condition.
In order to maintain this condition, as installer / user you must carry out your task in accordance
with the description in these instructions, technically correctly and with the greatest possible
precision .
We assume, as a trained specialist you are having mechanical and electrical knowledge!
Satisfy yourself that the armatures/vales will only be used within their admissible limiting value
(see the technical data) .
The armatures/valves must be used only for a purpose corresponding to their construction!
The armatures/valves must be used within the values specified in the technical data!
The operating of the armature/valve outside the nominal temperature range could destroy the
sealing and the bearings.
The operating of the armatures/valves outside the nominal pressure range could destroy the inner
parts and the body.
Never remove a cap or a other component part if the armature/valve will be under pressure.
Do not mount, start or adjust the armature/valve if itself, the pipes or a mounted actuator will be
damaged.
After the maintenance or repair check the right function of the armature/valve and the tightness
of the pipe connections.
Also check the function of the accessories e.g. actuators, limit switches, etc.
