Intrinsic safety valves can be used for applications that require similar explosion class/ignition degree to d2G4 or Exd II BT5 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.

1. Use with specified safety barrier.
For i2G4 explosion-proof valves, use them with MTL728+ safety barrier.
For Exia II BT5 explosion-proof valves, use them with the safety barrier SAF3-5 or that meets the
conditions described below (note *1).
2. Parts and connections cannot be changed.
3. Use 1 explosion-proof barrier for each solenoid valve.
