Features

  • Redundant coil design is ideal for applications requiring high availability and reliability
  • Coils are voted 2oo2
  • Energizing either one or both coils will cause the valve to shift and maintain the controlled device in the shifted position. In order to return the controlled device to the un-shifted position, both coils must be de-energized
  • Normally Closed constructions are SIL 3 capable, certified by Exida
