Solenoids group II for surface plants with gas, vapours and dust environment

  • ATEX 94/9/EC
    • Ex II 2 GD Ex d IIC T6/T4/T3,
    • Ex tD A21 IP67 - category 2, zone 1, 2, 21 & 22
  • IECEx worldwide recognized safety certification, Ex d IIC T6/T4/T3, Ex tD A21 IP67
  • Rostechnadzor Russian Certification 
    • Ex d IIC T6/T4/T3

Solenoids group I for surface, tunnels or mining plants

  • ATEX 94/9/EC: Ex I M2 Ex d I Mb
  • IECEx: EX d I Mb

The solenoid case is designed to contain the possible explosion which could be caused by the presence of the gas mixture inside the housing, thus avoiding dangerous propagation in the external environment. They are also designed to limit the external temperature according to the certified class to avoid the self ignition of the explosive mixture present in the environment. DHA and DLOH valves conform to SIL 3 safety level (TÜV approved). These solenoids are applied to hydraulic valves for application in explosion hazardous environments.
