Solenoid directional valves
type
DKE and DKER
direct operated, ISO 4401 size 10
Table
E025-0/E
Spool type, direct operated solenoid valves
available in two different versions:
DKE
basic version equipped with stan-
dard solenoids
DKER
high performance version equip-
ped with improved force solenoids
certified according the North
American standard
UL-CSA
(C UR US mark)
Configurations and construction
The valves are available in three or four
way configurations and with two or three
spool positions, see section
.
The spools
are interchangeable and
they are available in a wide range of
hydraulic configurations, see section
.
The solenoids
have two different execu-
tions for AC or DC power supply and they
are composed by:
• wet type screwed tube with integrated
manual override pin
(the tube are dif-
ferent for AC and DC power supply).
• AC and DC coils see section
The coils are interchangeable for the
same type of power supply AC or DC and
they can be easily replaced without tools
(they are not interchangeable between
DKE and DKER)
The coils are fully encapsulated with the
following temperature classes:
• class H for DC coils
• class F for AC coils
The valve body
is 5 chambers type,
made by shell-molding casting, CNC
machined with high tolerance accuracy and
then cleaned by thermal deburring.
The optimized internal flow paths, largely
cored with extrawide channels to the tank
port, ensure low pressure drops.
Options
The following optional devices are available for
DKE and DKER:
• prolonged manual override protected with
rubber cap for easy hand operation
• control devices of the valve switching time
• spool position monitor devices for safety
applications
• external drain port Y for high tank pressure
Surface mounting ISO 4401 size 10
Max flow up to 120 l/min
Max pressure: 315 bar
