    Type Description

    The 6520 EExi valves are used for process actuation in hazardous areas. Thanks to the intrinsically safe design and the choice of corrosion resistant materials, the valves can be used in a wide variety of demanding applications. The NAMUR flange allows easy mounting directly to process valves. Due to the low power consumption, up to 4 valves can be connected to the Profibus PA I/O-Box 8642. The circuit function of the 6520 can easily be changed from H (5/2-way) to C (3/2-way) simply by changing the adapter plate, which is within scope of supply.

    • II 2G EEx ia IIC T6 PTB01 ATEX 2194X approved
    • Low power consumption
    • 3/2- and 5/2-way
    • High flow rates
