CAUTION
Cold/hot pipelines and/or angle valves.
Risk of injury due to thermal influences!

Insulate the angle valve.

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.
Angle valve body leaking or broken!

Provide suitable support.

Additional loads, such as traffic, wind or earthquakes, are not explicitly taken into account by
default and require separate sizing.

Insulate the angle valve with diffusion-tight material.
Improper handling.
Leak or damage to the angle valve!

Do not store tools and/or other objects on the angle valve.

Do not use tools to increase the torque of the hand wheel.
Painting of the angle valve and pipelines.


Protect stem, plastic parts and type plate against the application of paint.
Impermissible stress
Damage to the control mechanism!

Do not use the angle valve as a foothold.
Exceeding the maximum permissible operating conditions.
Damage to the angle valve!

The maximum permissible operating pressure must not be exceeded, and the minimum and
maximum allowable working temperatures must be observed.

Create the welding/soldering seam 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 angle valve!

Take appropriate measures against contamination.

Remove contaminants from the pipes.
Incorrect earthing during welding work in the pipeline.
Damage to the angle valve (burned spots)!

Remove bonnet during welding.

When carrying out electric welding work, do not use functional parts of the angle valve for
