17.2 - Corrosion resistance
This version features the zinc-nickel coating on all exposed metal parts of the valve,
making it resistant to exposure to the salt spray for 600 hours (test performed according
to UNI EN ISO 9227 and assessment test performed according to UNI EN ISO 10289).
17.3 - DC coils
The coils feature a zinc-nickel surface treatment.
The WK7D coil includes a suppressor diode of pulses for protection from voltage peaks
during switching. During the switching the diode significantly reduces the energy
released by the winding, by limiting the voltage to 31.4V in the D12 coil and to 58.9 V in
the D24 coil.

(*) The IP69K protection degree is not taken into account in IEC 60529 but it is included
in ISO 20653.
NOTE: As regards the liquid ingress protection
(second digit), there are three means of
protection.
Codes from 1 to 6 are related to water jets.
Rates 7 and 8 are related to immersion.
Rate 9 is reserved for high pressure and
temperature water jets.
This means that IPX6 covers all the lower steps,
rate IPX8 covers IPX7 but not IPX6 and lower,
instead IPX9 does not cover any of them.
Whether a device meets two types of protection
requirements it must be indicated by listing both
the tests separated by a slash.
(E.g. a marking of an equipment covered both
by temporary immersion and water jets is
IP66/IP68).
