  Pneumatically operated valves:  
      Operating pressure 4 - 8 bar overpressure
      Response to power failure Valve closes and remains tight
      Response to compressed air failure Actual status remains: full open or full closed
      Supply voltage of solenoid valve Standard 24VDC
      Power consumption of solenoid valve 2,5 W
      Contact rating of position indicating switches 2 A (250VAC/24VDC)

*) Valve opens with this differential pressure. If pressure is higher, the valve don't open but no damage occurs.
