The modern DeltaV SIS delivers higher plant and personnel safety. How? DeltaV SIS extends the time between proof tests by giving users the power to perform partial stroke testing of valves automatically or manually. This option reduces the number of trips to the field for manual field testing, validation, and documentation of loops and field devices.


In addition to reducing effort and costs, this intermediate testing results in increased confidence that the valve will perform on demand without adding risk.


Partial stroke testing enables you to:

  • Confidently extend the time between proof testing while maintaining your risk reduction factor and reducing spurious trips.
  • Automate tests without additional wiring or components.
  • Record and maintain test results in the DeltaV SIS Event Chronicle.


Learn how testing fits into the complete safety lifecycle picture.
