Intrinsic safety valves can be used for applications that require similar explosion class/ignition degree to d2G4 or type (explosion-proof enclosure construction). Without need for expensive connection tools and complex installation work that are inevitable for explosion-proof enclosure types, the intrinsic safety valves achieve highly reliable explosion-proof performance.
