Use in safety-instrumented
systems (SIL)
Observing the requirements of IEC61508, the systematic capability of the pilot valve
for emergency venting as a component in safety-instrumented systems is given.
Use is possible on observing the requirements of IEC61511 and the required hard-
ware fault tolerance in safety-instrumented systems up to SIL2 (single device/HFT=0)
and SIL3 (redundant conguration/HFT=1).
