Diagnostics Predictive maintenance strategy compared to corrective and preventive
• Enhanced field device
availability
- No unplanned shutdowns
- Reduced unexpected
downtime
• More effective maintenance
resource allocation
- Concentrating on the devices
that really need to be
maintained
• Efficient maintenance planning
- Work lists in advance
- Human resources, spare parts
and equipment

UNCLASSIFIED
• Based on tests that are run during start-up and shut down
- any view of this test is an instant in time, it does not give predictive value and you can not plan the maintenance activities and need of spare parts in advance
• Valve is not under true process conditions and the analysis result does not reflect the real situation.
• Users do not have time to test, analyze and make decisions on every valve package during the shut-down

main diagnostics at
once
• Tells the condition of
the safety valve
• Indices are based on
the measurements and
the test data in VG
© Metso
VG9000 internal pneumatics test
• Tests VG9000 pneumatic operation
without moving the safety valve
• Safety action is available during
the testing
• Test is controlled by VG9000 and
is cancelled if the valve moves
• Automated or manual
• Can be run very often, because it
does not affect the process at all
