2 Safety
2.1 Intended use
Strainers are used to filter contamination out of media. The cleaning effect with this model depends on the
mesh size. The permissible operating conditions are specified in these operating instructions.
The valve is suitable for the media listed in these operating instructions; see section 4.5 "Media".
Operating conditions and applications deviating from these require the approval of the manufacturer.
Only media may be employed to which the materials used for the valve body and seals are resistant.
Contaminated media or usage outside of the pressure and temperature specifications can lead to damage
to the valve body and seals.
Avoidance of foreseeable incorrect use
Never exceed the permissible usage limits specified in the data sheet or in the documentation
with regard to pressure, temperature, etc.
Follow all safety instructions and operating procedures in these operating instructions.
2.2 Meaning of the operating instructions
The operating instructions are to be read and followed by the responsible technical personnel before
installation and start-up. As part of the valve the operating instructions must always be available close to
it. People could be seriously injured or killed if the operating instructions are not followed.
Read and observe the operating instructions before using the valve.
Retain the operating instructions and make sure they are available.
Pass on the operating instructions to subsequent users.

2.3 Instructions for people who work with the valve
People could be seriously injured or killed if the valve is used improperly. In order to avoid accidents, all
persons who work on the valve must meet the following minimum requirements.
They are physically capable of controlling the valve.
They can safely carry out the work with the valve within the scope of these operating instructions.
They understand the operating principles of the valve within the scope of their work and are able to
recognise and avoid the hazards of the work.
They have understood the operating instructions and are able to implement the information of the
operating instructions accordingly.
2.4 Personal protective equipment
Missing or unsuitable personal protective equipment increases the risk of damage to health and injuries to
people.
The following protective equipment is to be provided and worn during work:
Protective clothing
Safety shoes
Set out and use additional protective equipment depending on the utilisation and the media:
Safety gloves
Eye protection
Ear protection
Wear the specified personal protective equipment for all work on the valve.
2.5 Additional equipment and spare parts
Additional equipment and spare parts not conforming to the manufacturer's requirements can negatively
affect the operational safety of the valve and cause accidents.
In order to ensure operational safety, use original parts or parts that conform to the
manufacturer's requirements. If in doubt, have these confirmed by the dealer or manufacturer.
2.6 Adhere to the technical thresholds
If the technical thresholds for the valve are not adhered to, the valve may sustain damage, accidents may
be caused and people may be seriously injured or killed.
Adhere to the thresholds. See section 4 “Description of the valve".
2.7 Safety instructions
DANGER
Hazardous medium.
Escaping operating medium can lead to poisoning, burns and caustic burns!
Wear the prescribed protective equipment.
Provide suitable collecting containers.
Slipping of the valve out of the suspension.
Danger to life from falling parts!
Do not suspend the valve by the handwheel.
Note the weight specifications and the centre of gravity.
Only use suitable and approved load handling equipment.
WARNING
Harmful and/or hot/cold conveyed media, lubricants and fuels
Hazardous for persons and the environment!
Collect and dispose of rinsing medium and any residual media.
Wear protective clothing and a protective mask.
Observe legal regulations regarding the disposal of harmful media.

WARNING
Risk of injury if maintenance work is done incorrectly!
Incorrect maintenance can lead to serious injury and considerable material damage.
Before the start of work, ensure there is sufficient room for doing the work.
Ensure the space around the work is tidy and clean! Parts and tools in loose piles or lying around
are hazard sources.
If parts have been removed, take care to assemble correctly and re-install all attachment items.
Before putting back into service, ensure:
All maintenance work has been carried out and completed.
There are no persons in the hazard area.
All covers and safety devices are installed and operating correctly.
CAUTION
Cold/hot pipelines and/or valves.
Risk of injury due to thermal influences!
Insulate valves.
Attach warning signs.
Medium escaping at high speed and high/low temperature.
Risk of injury!
Wear the prescribed protective equipment
NOTICE
Impermissible stresses arising from operating conditions and extensions / added structures.
Leakage or rupture of the valve body!
Provide suitable support.
Additional loads, such as traffic, wind or earthquakes, are not explicitly taken into account by
default and require separate dimensioning.
Condensation in air conditioning, cooling and refrigeration plants.
Icing!
Blocking of the actuation mechanism!
Damage due to corrosion!
Insulate valves with diffusion-tight material
Improper handling.
Leaking valve or damage to the valve!
Do not store tools and/or other objects on the valve.
Do not use tools to increase the torque of the hand wheel.
Painting of valves and pipelines.
Functional impairment of the valve / loss of information!
Protect plastic parts and type plates from being painted over.
Impermissible stress
Damage to the control mechanism!
Do not use the valve as a foothold.
Exceeding the maximum permissible operating conditions.
Damage to the valve!
The maximum permissible operating pressure must not be exceeded, and the minimum and
maximum permissible operating temperatures must be observed.
Welding beads, scale and other contaminants.
Damage to the valve!
Take appropriate measures against contamination.
Remove contaminants from the pipes.
Incorrect earthing during welding work in the pipeline.
Damage to the valve (burned spots)!
Remove bonnet during welding.
When carrying out electric welding work, do not use functional parts of the valves for earthing.
Exceeding the maximum permissible operating temperature.
Damage to the valve!
Create the welding/soldering stepwise so that the warming in the middle of the body does not
exceed the maximum permissible operating temperature.
