         The NAMUR solenoid valves, Type 5470  NAMUR and Type 5470   Dimensions [mm] (see datasheet for further Details)
         NAMUR Ex i, are equipped with a NAMUR standard flange for easy direct
         mounting on process actuator. The devices of this series are made from
         high quality plastics.                                                          D

         The valve is intended for operation on 24V DC outputs via the intermedi-
         ate switching of a corresponding intrinsically-safe operating resource
         (isolating module or barrier). If required, request the “Recommended
         Barrier and Isolating Module” data sheet.
