ValVue Software

Not only does ValVue provide the ability to quickly and easily set up the SVI FF you can also
monitor operation and diagnose problems with ValVue's advanced diagnostic capabilities.

ValVue Standard Edition

ValVue Standard Edition software is downloadable and is used with each SVI FF for positioner
calibration and configuration. ValVue Standard Edition software is freeware. It provides
functions to properly set up and start up an SVI FF digital valve positioner on any type of
control valve, along with diagnostics, Sequence, Audit Trial, and Monitoring Device. After a 30
day trail period the Sequence, Audit Trial, and Monitoring Device functionality will become
inoperable.

Operational Overview

The SVI FF is a smart electro-pneumatic positioner that:
1. Receives a digital setpoint from the controller and compares the setpoint input to the
valve position reported by the position sensor.
2. Uses the position control algorithm to analyze the difference between the position
setpoint and position feedback and sets a servo signal for the I/P converter.
3. Uses the output pressure of the I/P, which is amplified by a pneumatic relay that drives the
actuator. Once the error between the setpoint and the valve position feedback is
eliminated, no other correction is applied to the servo signal in order to maintain valve
position.
The local explosion proof LCD/Buttons (if equipped) display provides information about the
device. The LCD can display data from blocks on other devices, if the system is so configured.
The switch board provides a user-configurable discrete output, which is optionally used to
indicate different controller states.
