operating and safety instructions
These instructions summarise the main
warnings concerning the routine operations as
per the related installation and maintenance
manual.
Storage
Warning
Storage in an open area for a limited period
can be considered only in case the valves have
appropriate packing (packed incases lined with
tarred paper, and contents well protected with
barrier sacks).
• Do not place consignment packages directly on
the ground.
• Do not expose consignment packages to the
weather or directly to the sun.
• Check the packages every two months.
Handling
Warning
• Before lifting or handling the valve, make sure
you have no limitations to do it.
• For valve handling and/or lifting, the lifting
equipment (fasteners, hooks, etc.) must be
sized and selected while taking into account the
valve weight indicated in the packing list and/
or delivery note. Lifting and handling must be
made only by qualified personnel.
• Caution must be taken during the handling
to avoid that this equipment passes over the
workers or over any other place where a
possible fall could cause damage. In any case,
the local safety regulations must be respected.

inStallation
important
• Verify that the direction of the flow of the line
corresponds to the arrow indicated on the
valve body.
• Valves without the arrow are bi-directional.
• It is recommended to perform piping flushing
before the valve installation. If this is not
possible, the valves must be set with the disc in
full open position before starting with flushing.
• If piping system is pressurized with water for
testing, and in case the piping system has been
shut down after testing for a long time, the
following recommendations should be adopted:
a. Use corrosion inhibitor with water to
pressurize the piping system
b. After testing, the piping system should be
depressurized and the test water completely
drained.
• For operating temperatures above 200°C
(392°F) a thermal insulation of the body is
recommended.
maintenance
Warning
• Depressurize the line before starting any
maintenance. Failure to do so may cause
serious personal injury and/or damage to the
valve.
• In case of valve removal, depressurize the line
before starting any operation with the valve in
open position. Then, close the valve.
