1.1.4 Minimised process variability
Linearisation of the valve flow characteristics
Excellent dynamic and static control performance
High-speed of response
Accurate internal measurements
1.1.5 Easy installation and configuration
Same unit for linear and rotary valves, double and
single-acting actuators
Simple calibration and configuration
using Local User Interface (H, F, P)
using DTM or EDD in a remote location (H, F)
see 375/475 menu structure from annex 1
using Profibus configurator like Simatic PDM (P)
or DTM
Low power design enables installation to all com-
mon control systems
Ability to attach options to electronics and mechan-
ics later
Possibility to mount also on valves that are in pro-
cess with 1-point calibration feature
1.1.6 Open solution
Metso is committed to delivering products that freely inter-
face with software and hardware from a variety of manufac-
turers; and the ND9000 is no exception. This open
architecture allows the ND9000 to be integrated with other
field devices to give an unprecedented level of controllability.

1.1.7 ND9000 in fieldbus networks
Approved interoperability
Host interoperability ensured
F
OUNDATION
fieldbus ITK version 6.1.2 certified
Profibus PA profile version 3.0 PNO certified
Easy to upgrade; can be done by replacing the HART
communication board to fieldbus communication
board
Excellent maintainability with firmware download
feature
Advanced communication diagnostics
Digital communication via the fieldbus includes not
only the set point, but also the position feedback sig-
nal from the position sensor. No special supplemen-
tary modules for analog or digital position feedback
are needed when using the fieldbus valve controller.
Back up LAS functionality available in F
OUNDATION
fieldbus enviroment
Input selector and output splitter blocks available in
F
OUNDATION
fieldbus devices allowing advanced dis-
tributed control
Multipurpose functionality
Standard function blocks enables the freedom to
use ND9000 intelligent valve controller either in
continuous or on-off control applications
Open and close information directly available via
the fieldbus
Open and close detection is based on either posi-
tion measurement (soft limit switch) or mechani-
cal limit switch information

Excellent temperature characteristics
Vibration and impact tolerant
IP66 enclosure
Protected against humidity
Maintenance free operation
Resistant to dirty air
Wear resistant and sealed components
Contactless position measurement
1.1.9 Predictive maintenance
Easy access to collected data with FDT based DTM
Unique Online Valve Signature to detect valve
friction even more accurately.
Performance view with report, which gives
guidelines for recommended actions.
Logical trend and histogram collection
Information collected on service conditions
