The valve meets the requirements of the European Direc-
tive 2014/68/EU relating to pressure equipment, and has
been marke
d according to the Directive.
1.7 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 valve performance limitations!
Exceeding the limitations marked on the valve may cause
damage and lead to uncontrolled pressure release. Dam-
age or personal injury may result.
CAUTION:
Do not dismantle the valve or remove it from the
pipeline while the valve is pressurized!
Dismantling or removing a pressurized valve will result in
uncontrolled pressure release. Always isolate the relevant
part of the pipeline, release the pressure from the valve
and remove the medium before dismantling the valve.
Be aware of the type of medium involved. Protect yourself
and the environment from any harmful or poisonous sub-
stances. Make sure that no medium can enter the pipeline
during valve maintenance.
Failure to do this may result in damage or personal injury.
CAUTION:
Beware of the segment movement!
Keep hands, other parts of the body, tools and other
objects out of the open flow port. Leave no foreign
objects inside the pipeline. When the valve is actuated,
the segment functions as a cutting device. The segment
position may also change when the valve is moved. Close
and detach the actuator pressure supply pipeline for valve
maintenance. Failure to do this may result in damage or
personal injury.
CAUTION:
Protect yourself from noise!
The valve may produce noise in the pipeline. The noise
level depends on the application. It can be measured or
calculated using the Metso Nelprof software. Observe the
relevant work environment regulations on noise emission.
CAUTION:
Beware of a very cold or hot valve!
The valve body may be very cold or very hot during use.
Protect yourself against cold injuries or burns.
CAUTION:
When handling the valve or the valve package, take its
weight into account!
Never lift the valve or valve package by the actuator, posi-
tioner, limit switch or their piping.
Place the lifting ropes securely around the valve body (see
Fig. 13). Damage or personal injury may result from falling
parts.
