Acc. to pressure directive 97/23/CE, the device can only
be used in the following cases (depending on the max.
pressure, the DN of the pipe and the fluid):
type of fluid conditions
Fluid group 1 § 1.3.a Only DN ≤ 25
Fluid group 2 § 1.3.a DN ≤ 32
or DN > 32 and PNxDN ≤ 1000
Fluid group 1 § 1.3.b DN ≤ 25
or DN > 25 and PNxDN ≤ 2000
Fluid group 2 § 1.3.b DN ≤ 400

Pipe diameter DN20 (except for DN20 specified
p.27) to DN400. The appropriate
diameter is determined using the flow
rate / DN / fluid velocity graphs.
Pressure class Depends on the material of the fitting
used and on the fluid temperature.
