1.8 Safety precautions
CAUTION:
Do not exceed the valve performance limitations!
Exceeding the limitations marked on the valve may cause
damage and lead to uncontrolled pressure release.
Damage 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 people and
the environment from any harmful or poisonous substances.
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 ball cutting 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 ball functions as a
cutting device. Close and detach the actuator pressure supply
pipeline for valve maintenance. Failure to do this may result
in damage or personal injury.
CAUTION:
Beware of noise emission!
The valve may produce noise in the pipeline. The noise level
depends on the application. It can be measured or calculated
using the Metso Automation Nelprof computer program.
Observe the relevant work environment regulations on noise
emission.
CAUTION:
Beware of extreme temperatures!
The valve body may be very hot or very cold during use.
Protect people against cold injuries or burns.
CAUTION:
When handling the valve or the valve package, bear
in mind its weight!
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. 10).
Damage or personal injury may result from falling parts.
The weights are shown on pages 14–22.
CAUTION:
Follow the proper procedures when handling and
servicing oxygen valves.
2 TRANSPORTATION, RECEPTION
AND STORAGE
Check the valve and the accompanying device for any damage
that may have occurred during transport.
Store the valve carefully. We recommend storing indoors in a
dry place.
Do not remove the flow port protectors until installing the valve.
Move the valve to its intended location just before installation.
The valve is usually delivered in the open position.
