DESCRIPTION
ORDERING CODE
Valves EVX-*-C5 are ATEX directional control valve in cartridge style poppet
type. It is suitable for 2 way metric cavity M22 x 1,5 or cavity SAE 08 . The valve
is available with ATEX metallic DC and AC solenoids. The coil is Zinc-nichel
coated for an enhanced surface protection (ISO 9227, 520 h salt spray).
Protection according to IEC 144: Class IP67- External surfaces zinc-nickel coat-
ed (min. thickness 7 micron)
Connection: 3,5 mm
2
wire cable (CEI 20-22), length 3 m already connected to coil.
Electrical connection must be accordance to Ex-proof norm ATEX. Earth
connection both internal, with yellow-green wire in the cable,and external with a
minimum 4mm
2
cable fastened to earth screw.
