Masoneilan SVI3 Digital Valve Positioner

The third generation Masoneilan SVI3 Digital Valve Positioner is a user-friendly digital valve positioner for pneumatic control valves.  Utilizing advanced control and diagnostic algorithms, along with field-proven noncontact position sensing technology, the Masoneilan SVI3 Digital Valve Positioner delivers accurate, responsive, and reliable positioning performance.

Product Features

Masoneilan SVI3 Digital Valve Positioner has the following features:

Reliable and Accurate

Build on 20+ years and billions of hours of field-proven valve position sensing technology, control algorithms, and advance performance pneumatic design, extended temperature range down to -55 degC

Increases Plant Efficiency

Online Valve diagnostics – 19 new diagnostics to continuously monitor valve health while the Masoneilan SVI3 Digital Valve Positioner is in operation. Data Storage – up to 1 year of diagnostic data stored within the device – trend and identify valve problems before they impact plant operation. Improved pneumatic performance – 40% reduction in steady-state air consumption, with a 15% increase in air delivery.
