8.2.5 Bolt lengths for flange connections
Connecting elements are needed to install a valve in a pipeline. These are bolts and
nuts. For BOA-SuperCompact fully threaded studs with nuts can also be used (see
type series booklet 7113.1).
The bolts and nuts must be selected in accordance with DINEN1515-4 "Flanges and
their joints, Part4, Selection of bolting". In order to ensure the correct installation of
the valve, the bolts and nuts must be made of the materials defined by this standard
as a function of pressure and temperature for use within the scope of the Pressure
Equipment Directive 2014/68/EU.
The bolt lengths are specified without considering tolerances; they refer to the
installation of a valve in a pipe with a standardised steel mating flange to
DINEN1092-1.
The number of bolts, their thread size and length are specified for the respective
valve series and nominal pressures. This data can also be obtained via KSB's flange
selector (reference No. 0570.3).
