1.1 Scope of the Manual
This Manual has been prepared by the Manufacturer to provide the operating technical information for instal-
lation, operation and maintenance of the valve concerned.
The Manual, which is an integral part of the valve concerned, must be preserved throughout the life of the valve

If the valve concerned changes ownership, the Manual has to be handed over to the new owner as part of the
valve supply.
The Manual is meant for specialist technical personnel appointed and authorized by the Manufacturer, owner
and installer to act on the valve concerned for which specic technical skills in the sector concerned are neces-
sary (electrical, mechanical, etc.).
The illustrations may di󰀨er from the actual structure of the valve concerned but do not interfere with the expla-
nation of the operations.
In case of doubt, contact the Manufacturer for explanations.
The Manufacturer reserves the right to make changes to the Manual without the obligation to provide prior
notication, except in case of modications concerning the safety level.
The technical information included in this Instruction Manual is the property of the Manufacturer and therefore
has to be considered as condential.
It is forbidden to use the Manual for purposes other than those strictly linked to the operation and maintenance
of the valve concerned.
This information is provided by the Manufacturer in the original language (English) and can be translated into
other languages to satisfy legislative and/or commercial requirements.
