Category ia
Ignition must not be
provoked during normal
operation, nor in the
presence of a single fault,
nor in the presence of a
combination of faults.
Group II
Electrical apparatus for
places with a potentially
explosive atmosphere, other
than mines susceptible to
firedamp.
General information
Low consumption (0.7W), CROUZET 3/2 miniature solenoid valves
comply with European Standards EN 50014 and EN 50020 relating
to equipment operating in potentially explosive atmospheres.
These intrinsically safe products are recommended for the
chemical, petrochemical, gas and mining industries, etc.
Recommended barriers and interfaces
These CROUZET recommended safety barriers and interfaces can be obtained from the manufacturers indicated below. When ordering, specify that
they are to be used to supply miniature solenoid valves (type 81 519) EEx ia II C T6, LCIE no. 93.C6014 X.

Important :
These intrinsically safe miniature solenoid valves must be
individually connected to an approved safety barrier. Placed in a
safe zone, these barriers make it possible to supply intrinsically
safe miniature solenoid valves installed in a hazardous zone.
Safety description (to LCIE approval no. 93 C 6014 X)
U supply = source of intrinsically safe supply to the miniature solenoid
valve.
I max. / coil = maximum current across the coil.
The electrical connection between the safety barrier (or interface) and
the miniature solenoid valve can be made with ordinary wires or
cables. The inductance of the connecting line between the safety
barrier and the solenoid valve must be less than 0.5 mH.
