Safety notes
The ball valve has to be exercised at least once a week, so that the quality of potable water as well as the
functionality are not affected.
Product features
The on/off ball valve is adjusted by a rotary actuator. The rotary actuator is connected by an on/off signal.
Open the ball valve counterclockwise and close it clockwise.
Installation notes
The ball valve is a regulating device. To fulfil this control task in the long term, the circuit must be kept free
from particle debris (e.g. welding beads during installation work).
The ball valve can be installed upright to horizontal. The ball valve may not be installed in a hanging
position, i.e. with the stem pointing downwards.
