Safety instructions and safety measures
Damage to the ball valve due to an impermissible pressure in-
crease!
The ball valve body may contain small amounts of medium in the
closed and open position.
Ö
Use a ball valve with an optional relief bore if it is possible
that the closed area of the ball
fi
lled with medium can heat
up due to external heat. This prevents an impermissible pres-
sure increase due to a change in the condition of the unit.

Unsuitable tools can damage the ball valve.
Ö
Suitable tools are required to work on the ball valve, see
Chapter “15.1.3 Tools”.
Damage to the ball valve due to unsuitable lubricants!
Unsuitable lubricants can corrode and damage the surface.
Ö
The ball valve material requires suitable lubricants, see Chap-
ter “15.1.2 Lubricants”.
