What is an actuator?
2
Core Functionality
Definition
• Operate a valve
• Protect the valve
• + To give performance information
by getting data and storage in a
Datalogger
• Mechanical, electro-mechanical,
hydraulic, pneumatic or manual device
to operate a valve
Main Parameters
• Power supply
• Control mode
• Movement type
• Atmosphere

3
How do we store the
information?

Datalogger
4
Core Functionality
Definition
• To provide data to identify faults
• To provide data for predictive failure
• Historical register with all the sensed
information

Advanced analytics
to improve reliability
and availability of
key assets.
“Industry research
forecasts a 13.8%
cost reduction
based on average
customer
maintenance spend
over a comparable
period.”

Introduction to Rotork’s Intelligent Asset
Management
10
• Cloud-based system
• Helps reduce unplanned downtime
• Advanced condition monitoring provides easy and accurate
reporting of the condition of valves/flow control assets
• Can improve long-term operational stability of all assets
• Planned maintenance strategy with advanced analytics
• Proactively managing and fixing key assets before they
become problematic

Immediate summary of asset condition
11
Rotork Managed Solution – Landing Page Summary
Customer Benefits
• Quickly identify
problem assets to
save time
• Visual, interactive
interface for fast
learning curve
• Easy to engage
with Rotork
• Clear indication
avoids uncertainty

Easy to access and interpret information
12
Rotork Managed Solution – Visual Interface
Customer Benefits
• Clearly presented information saves time and resource
• Easy to interpret what is good and bad for quicker fix
• Comparison of sites and areas allows quick identification
of poor performance
Plantwide view; pins show exact
location and health colour code
Location can be set using GPS
coordinates or drag-and-drop map
Summary views simplify complex
analytics into easy to interpret visuals
Deep dive data is
accessible if required

Torque is critical to valve operation
13
Rotork Managed Solution – Torque Analytics
Customer Benefits
• Decision on acceptable levels automated and clearly
indicated enabling remedial action before failure
• Sensitive algorithms detect subtle changes well below
limits and alert user to prevent future failure
Detailed Vibration
Log data analysed
and key measures
shown
Critical level clearly
shown
Multiple datalogs
analysed at once to
determine changes
over time

Temperature is environment related
14
Rotork Managed Solution – Temperature Analytics
Customer Benefits
• Removes need to manually review data, saving time
• Changes can indicate site issues including failed thermal
insulation, failed cooling systems, process variation
• Early detection of changes can save costly repairs
Maximum level and good /
warning / alert levels
calculated & clearly shown
Simple access via Analytics tab
and selecting Temperature
Temperature is used as a
factor when assessing
overall condition
Datalog data automatically
analysed

Vibration can cause serious faults
15
Rotork Managed Solution – Vibration Analytics
Good / warning /
alert levels
individually
calculated for
each axis
Detailed datalog information
automatically analysed
Vibration is a key cause of
contactor and motor failure
Data normalised
for mounting
orientation
Customer Benefits
• Early detection of issues, allowing resolution before
costly failure
• Detection of excessive vibration  This is not reported
by actuators as a fault, so could be undetected and lead
to failure
• Detection of intermittent vibration not present during
commissioning

Summary of Rotork’s Intelligent Asset
Management
16
Confidential
• Advanced analytics removes the need to
manually review data, saving time
• Increased asset condition knowledge,
reducing risk
• Fast access to actionable insight and
recommended actions
• Single location to monitor many actuators
• Early detection of issues allows resolution
before costly failure, saving money and
reducing downtime
• Enables continued delivery of high quality
flow control across multiple applications
• Applicable to all markets
• Desalination Plant in Barcelona – Spain . /
