WARNING
Danger of crushing hands
and other body parts!
There is a risk of injury during as-
sembly/disassembly by movements of the
ball. The shut-off body (e.g. ball or disc) of
the valve works as a separating element.
It makes no difference whether a rotary
actuator is mounted or not. The position
of the ball may change during transport or
handling of the valve.
• Keep hands and fingers away with the
compressed air supply connected.
• Always disconnect the compressed
air supply from the rotary actuator
before carrying out maintenance and
repair work on the valve and when
installing and removing the ball valve
from the pipeline.
• Pay attention to movements of the
ball.
•
Keep hands, other body parts, tools
and other objects out of the swivel
range of the ball. Do not leave any for-
eign objects inside the pipeline.
• Perform works carefully when assem-
bling, disassembling and sampling.
WARNING
Flying parts!
Splashing medium!
There is a risk of injury when the valve is
removed under pressure or with present
medium. The disassembly or removal of a
pressurised valve causes an uncontrolled
pressure drop.
• Do not disassemble or remove the
valve from the pipeline as long as the
valve is pressurized.
• Always isolate the respective valve in
the piping system.
• Depressurise the valve and remove
the medium before working on the
valve and the rotary actuator.
WARNING
Ejected parts!
When adjusting the rotary actuators and
when the rotary actuator is opened un-
der pressure, there is a risk of parts being
ejected!
• Always disconnect the compressed
air supply before maintenance, disas-
sembly and repair!
• Never set the mechanical end posi-
tions on the actuator as long as there
is pressure on connection 2 or 4.
• Make sure the pinion of the rotary ac-
tuator is moving in the correct direc-
tion.
