Type description : ATEX Valves 3/2, 5/2 and 5/3-way ATEX approved valves
For use in explosion hazardous environment Mechanically and pneumatically actuated valves Solenoid valves, NAMUR valves Ex nA, Ex iA, Ex m, Ex e mb, Ex dm, Ex d
Ignition protection : c = Constructional safety/ general protection for mechanical ATEX,
i = Intrinsic safety/ called ia for solenoids,
na = Non sparking,
m = Encapsulation/ with cable,
me = Encapsulation enhanced safety/ called Ex emb with junction box,
d = Flameproof enclosure/ with junction box,
dm = Flameproof encapsulation/ with junction box
