Observe the limits in the test certificate for explosion-protected versions.
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 configuration/HFT = 1).
