solenoid valve
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
hardware fault tolerance in safety-instrumented systems up to SIL 2 (single de
