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.

2.4 Information for use

2.4.1 Corrosion

Operating temperature [T

Operating pressure [P

] 110 °C

max

] 1.6 MPa (16 bar)

max

Scope according to applicable regulations, see Ä „Regulations from

section: Technical data“ on page 7

n Operating temperature: 90 °C
n Operating pressure: PN 10 (10 bar)

Overground pipelines and fittings in rooms do not normally require
external corrosion protection.

There are exceptions in the following cases:

n Contact with aggressive building materials such as nitrite or mate‐

rials containing ammonium

n In aggressive surroundings

If external corrosion protection is required, observe the pertinent guide‐
lines, see Ä „Regulations from section: Corrosion“ on page 8.

2.5 Optional accessories

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).

The following optional accessories are available:

n actuating lever made of metal
n Easytop thermometer
n Easytop media marking
n Protective caps for the actuating lever made of plastic in red and

green for the identification of the corresponding area of use

n Insulating shells
