Body identification:
The shell bears the following information in
accordance with DIN EN 19 and AD 2000, A4:
nominal diameter
nominal pressure
shell material
manufacturer's identification
charge number/foundry identification
Cast 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
02 = Year of certification (here: 2002)
871 = Certification number (here: 871)
d0 = Narrowest flow Ø in mm (here: 40)
D/G = intended for discharging vapours/gases
F = intended for discharging liquids
w
= Certified coefficient of discharge
(here: 0.82 for D/G and 0.55 for F)
p = Test pressure in bar (here: 6.0)
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:
