1.1 Type plate, CE and body
markings
The stainless steel name plate is undetachably riveted
to the body.
Another stainless steel tag plate riveted to the valve
indicates the test pressure.
If the operator attaches his identification, it must be
ensured that the valve matches the application in
question.
Example of type plate with CE marking:
Body identification :
The following are visible on the body according to DIN
EN 19 and AD 2000 A4:
♦
Nominal size
♦
Rated pressure
♦
Body material
♦
Manufacturer's identification
♦
Melt number/Foundry identification
♦
Foundry date
♦
Arrow for direction of flow
1.2 Component identification
Certified safety valves KSE/F and KSE-C/F are
identified with a certification plate to the German data
sheet A2 (on pressure vessels). This stainless steel
plate is riveted to the valve body.
It contains the following details for example:
TÜV
= TÜV symbol
SV
= Safety valve
11
= Year of certification (here: 2011)
871
= Certification number (here: 871)
d0
= Narrowest flow Ø in mm (here: 40)
(S)D/G = intended for discharging vapours/
gases
(L)F
= intended for discharging liquids
α
w
= Certified coefficient of discharge
(here: 0.82 for (S)D/G and 0.55 for (L)F)
%
= Opening pressure difference (here 10%)
A
= Narrowest flow cross section
(here 1257 mm
2)
Lift
= (here 13 mm)
p
= Test pressure in bar (here 10 bar)
1.3 Tightening torques
All screws greased, tighten in diametrically
opposite sequence!
The tightening torques for pipe screws and body
screws mentioned must not be exceeded. For an
exception, see
Section 8
, Flange connection valve /
pipe is leaking.
The following tightening torques are recommended.
