Valve certifications

A tightness certificate and an EN/DIN 50049 3.1 B cer-
tificate for the valve body and bonnet can be supplied
on request.

1.6

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.

1.7

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.

Safety precautions

 

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.

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 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 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 actu-
ated, 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 Nelprof com-
puter program. Observe the relevant work environ-
ment 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,
positioner, limit switch or their piping.
Place the lifting belts securely around the valve body
(see Fig. 5). Damage or personal injury may result from
falling parts. The weights are shown in Section 11.

CAUTION:
Follow the proper procedures when handling and
servicing oxygen valves.
