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 impermeable material
Improper installation.
Damage to the valve!
Remove cover caps before installation.
Clean the sealing surfaces.
Protect the body against impacts.
Painting of valves and pipelines.
Functional impairment of the valve / loss of information!
Protect spindle, plastic parts and type plate against the application of paint.
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.
Create the welding/soldering stepwise so that the warming in the middle of the body does not
exceed the maximum permissible operating temperature.
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.
