The safety version that every ESD valve has been waiting for
When you have emergency shutdown valves that must close in 2 seconds and you need proof they still work, the DVC6200 SIS is the answer. It runs partial stroke tests automatically, logs the results, and gives you a nice report for the inspector. No more sending a guy out with a laptop every month – it does it by itself. Refineries and offshore platforms have been using it for 15 years without a single missed trip.
| SIL rating | SIL 3 with single unit |
| PFDavg | less than 5*10⁻⁴ |
| Partial stroke | 1–90% configurable |
| Test interval | 1 day to 10 years |
Q: Do I need two positioners for SIL 3?
A: No – one DVC6200 SIS is certified SIL 3.
Q: Does it log the test results?
A: Yes – date, time, stroke time, everything stored forever.
