1.5 Valve approvals
X-series ball valves meet the requirements set by ASME B 16.34.
Fire safety characteristics are designed according to API 607 and BS
6755.
1.6 CE marking
The valve meets the requirements of the European Directive 2014/
68/EU 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.

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 Neles
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, positioner,
limit switch or their piping. Place the lifting ropes securely around
the valve body (see Fig. 7). Damage or personal injury may result
from falling parts.
The weights are shown on pages 13–15.
CAUTION:
Follow the proper procedures when handling and servicing
oxygen valves.
