Manufacturer
KROMBACH GmbH & Co. KG
Material
E.g. 1.4408
= casing material
Factory No.
E.g. 34082-2005
= consecutive production no. - year of
production
DN
DN (and numerical value)
Numerical value in mm, e.g. DN200 or
in inches, e.g. 8”
PN /class
Numerical value for PN / class
PN / class = dimension standard for
flanged butterfly valves (not: pressure
range!)
PS
Numerical value in bar
= pressure, upper limit of use for “TS”
TS
Numerical value in °C or °F
= temperature, upper limit of use for
“PS”
Code
E.g. KKS no.
Armatures which are subject to CE labelling are additionally labelled with

Conformity
CE, 0045
CE = manufacturer’s declaration
0045 = “notified body” - TÜV
In order that the armature can always be identified, the type label must not become damaged.
5. Transport and storage
Armatures must be handled, transported and stored with care:
⇒
the armature must be stored in its original packaging and/or stored with the protective caps on the
flange connections/butt welding ends. The armature should be stored and transported on a pallet
(or similarly supported) (even at the installation site).
⇒
when storing before installation, valve must be stored in a sealed dry space.
⇒
the metallic seat of the armature, the oil brake and the flange connection surfaces/butt welding
ends in particular must not become damaged either by mechanical or by other influences.
⇒
valves must be stored in the same way as they were delivered. The valve must not be started.
⇒
transportation must be carried out with care and in accordance with the local safety regulations.
⇒
for armatures with a larger nominal value, attachment and positioning of the armature must be
carried out with suitable hooks and lines the weight must be balanced in order to prevent
armatures from falling from the transport.
Danger
valves which are supplied without drive:
the armature must be transported particularly carefully. The unsecured valve disc
can open itself from the closed position under external influence (e.g. concussion).
Danger
to life
The means used to lift and transport the armature, such as hooks, lines, etc., must
be selected taking into account the weights specified in the delivery note and must
be adequately dimensioned. Lifting and transport may only be carried out by
qualified personnel.
