2.2 Intended use
Coordinate the use of the model for areas of use and media
other than those described with the Viega Service Center.
A ball valve is a fitting that is able to shut-off and open individual pipe‐
line sections through a 90° movement. The ball valve is not a control fit‐
ting and cannot be used for regulating volume flows. The ball must not
be in an intermediate position.
NOTICE!
Opening and closing the ball valve quickly can cause pres‐
sure shocks in the system.
– Always open and close the ball valve slowly.

lines, see Ä „Regulations from section: Corrosion“ on page 8.
Easytop fittings made of gunmetal/silicon bronze are suit‐
able for all types of potable water.
The chloride concentration in the medium must not exceed
a maximum value of 250 mg/l.
This chloride is not a disinfectant, but in fact pertains to the
content in sea and table salt (sodium chloride).
