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:
Example : Second name plate
No CE marking is permissible for the sizes 15, 20 and
25; the name plate therefore has no CE marking.

EN 19 and AD 2000 A4:
