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.

   Note1

   in the case of other barriers and combination

   Konan 454, 414, 416 series intrinsic safety solenoid valves have passed equipment qualification tests for intrinsic safety solenoid valve.

   the valves can be used in combination with the safety barrier that meets the following conditions. (the valves can be used with insulation barrier that does not need type A ground.)

   the barrier used in combination with the valves should be the one that has passed equipment qualification tests for a barrier and that meets the following conditions.

   Safety retention voltage

   Maximum voltage of a intrinsic safety circuit

   Less than 29.4V

   Maximum current of a intrinsic safety circuit

   Less than 93.8mA
