1.1 Name plate, CE and body
markings
The stainless steel name plate is undetachably riveted
to the body.
If the operator attaches his identification, it must be
ensured that the valve matches the application in
question.
Example of name plate with CE marking:
No CE marking is permissible for the sizes 15, 20 and
25; the name plate therefore has no CE marking.
Example: Name plate for control data
If heavy-duty bellows are installed, another name
plate indicates this:
HD - BVA = Heavy-duty bellows with support rings
of stainless steel
HD - BKo = Heavy-duty bellows with support rings
of PTFE/carbon

The following are visible on the body according to DIN
EN 19 and AD 2000 A4:
Nominal size
