Packing components
V-control ball
Options :
Richter ENVIPACK double packing
for particularly high safety requirements, self-
adjusting.
On request, monitoring and flushing connection.
Ball/stem unit extension for insolated pipes
Hand lever extension depending on requirements
Limit switches
for remote monitoring of hand and remote-
activated ball valves.
Lockable hand lever
to prevent unauthorised operation.
Stainless steel heating jacket
can be retrofitted, suitable for all common heat
carriers.
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.
