CE marking
The valve meets the requirements of the European
Directive 97/23/EC relating to pressure equipment, and
has been marked according to the Directive.
1.6
Recycling and disposal
Most valve parts can be recycled if sorted according to
material. Most parts have material marking. A material list is
supplied with the valve. In addition, separate recycling and
disposal instructions are available from the manufacturer. A
valve can also be returned to the manufacturer for recycling
and disposal against a fee.

CAUTION:
Do not exceed the performance limitations!
Exceeding the performance limitations marked on the
valve may result in valve damage or even in uncon-
trolled pressure release. Damage or personal injury
may result.
CAUTION:
Do not remove or dismantle a pressurized valve!
Removing or dismantling a pressurized valve will cause
an uncontrolled pressure release. Always shut off the
pipeline, release the pressure and remove the
medium before removing or dismantling the valve.
Identify the medium, protect yourself and the environ-
ment against any harmful or poisonous substances.
Prevent the medium from entering the pipes during
maintenance.
Failure to do this may result in damage or personal
injury.
CAUTION:
Beware of the cutting movement of the ball!
Keep hands, other parts of your body, tools and other
objects out of the open flow port. Also make sure that no
foreign objects enter the pipeline. Close and detach the
actuator pressure supply for maintenance.
Failure to do this may result in damage or personal injury.
CAUTION:
Protect yourself against noise!
The valve may produce noise in the pipeline. Its level
depends on the application and can measured or cal-
culated using the Metso Nelprof computer program.
Occupational safety regulations on noise levels
should be observed.
CAUTION:
Beware of extreme temperatures!
The valve body may be very hot or very cold. Protect
people against frostbites and burns.
CAUTION:
When handling the valve or the valve package,
remember its weight!
Do not lift the valve or the valve package from the
actuator, positioner, limit switch or their pipes. When
lifting the valve, place the lifting ropes around the
valve body. See Figure 5.
Damage or personal injury may result from falling
parts.
Valve weights are listed in Section 11.
CAUTION:
Follow the proper procedures when handling and
servicing oxygen valves.
