For correct operation of AC version, the valve must be filled with hydraulic fluid, otherwise some vibra-
tions may occur. In this case fill the valve with oil by opening the screw
, see sketch at section

NOTES

Options
A
= Solenoid mounted at side of port B (only for single solenoid valves). In standard versions, solenoid is mounted at side of port A.
WP
= prolonged manual override protected by rubber cap - see section
.
L, L1, L2, L3, LR
, see section
= device for switching time control (only for DC solenoids).
F *
= with proximity switch for monitoring spool position: see tab. E110.
Y
= external drain to be selected if the pressure at T port is higher than the max allowed limits (depending to the solenoid type) see “Operating limits” at
section
.

Type of electric connectors DIN 43650, to be ordered separately -
see section
.
SP-666
= standard connector IP-65 for direct connection to electric supply source.
SP-667
= as SP-666, but with built-in signal led.
SP-669
= with built-in rectifier bridge for supplying DC coils by alternate current (AC 110V and 230V - Imax 1A).
3 Spools
- spools
type
0/2, 1/2, 2/2
are only used for two position valves: single solenoid valves, type DKE*-163*/2; double solenoid valves type
DKE*-170*/2 and DKE*-175*/2.
- spools
type
0
and
3
are also available as
0/1
and
3/1
with restricted oil passages in central position, from user ports to tank.
-
spools type
1
is also available as
1/1
, properly shaped to reduce the water-hammer shocks during the switching.
-
other types of spools can be supplied on request.

Any position for all valves except for type - 170* (without springs) that must be installed with horizontal
axis if operated by impulses
(1) In case of 60 Hz voltage frequency the
performances are reduced by 10÷15% and
the power consumption is 80 VA for DKE and
90 VA for DKER.
(2) Average values based on tests performed at
nominal hydraulic condition and ambient/coil
temperature of 20°C.
(3) When solenoid is energized, the inrush cur-
rent is approx 3 times the holding current.
Inrush current values correspond to a power
consumption of about 280 VA for DKE and
320 VA for DKER.
