Conformance to Global Standards
In Pursuit of Safety (conforms to overseas standards) and Easy Use
Conformance to Global Standards
You can depend on solenoid valves of
NACHI brand.
Recognized by reliable overseas
safety standards such as CE (Europe),
UL (U.S.A.) and CSA (Canada).
Improved water proof
properties
The packing is designed to be
mated with the plate groove.
Improved setscrews
The setscrews are not disengaged
even if they are excessively
loosened.
Pursuit of safety
The terminal block has
been modified to improve
the insulation performance.
(Conforms to overseas
standards)
Available M12 connector
makes wiring simple.
Improved shape of cable
entrance
The cable entrance slope has been
made less sharp to ensure easy
cable connection.
Improved
legibility of
nameplate
More convenient due to
effective use of "Name
Plate Installation Hole"
You can fix the work
instruction nameplate directly.
You can place the plate there
temporarily during wiring
work. This will prevent the
plate from being lost.

Features
Features
CE-, UL- and CSA-recognized
1. Easy use
An expanded wiring space ensures easy
wiring.
Use of a 4-pin M12-connector (IEC60947-5-2)
permits one-touch connection of wires.
(Compatible with special parts)
Redesigned terminal box improves waterproof
properties.
2. Low power consumption
The power consumption of the DC solenoid (D
and E ) is reduced, with high voltage and
heavy current kept unchanged. This will further
promote your energy saving policy.
3. Reliable switching
An innovative fluid reaction compensating
mechanism assures reliable valve switching.

SpecificationsHandling
Note: The maximum flow rate of each valve varies according to the pressure. For details, see
page 10.
zTo make an effective use of the
wet type solenoid valve, connect
the pipe so that the T(R) port is
always filled with oil. Do not plug
the T(R) port.
xTake appropriate measures to ensure
that abnormal surge pressure in
excess of the maximum permissible
backpressure does not occur to the
T(R) port.
cPlease note that the maximum
flow rate is subjected to restriction
when you use a four-way valve as a
two-way or one-way valve by
blocking each port.
vKeep the hydraulic oil clean at all
times.
(Level of contamination: equal to
or better than NAS 12 class)
bUse the petroleum based hydraulic
oil conforming to Class 1 or 2
according to JIS K2213.
nWater or glycol based hydraulic oil
can be used for the standard valve.
In this case, pressure must not
exceed 31.5 MPa; further the flow
rate must not exceed 80 % of the
maximum flow rate. If you want to
use other flame resistant hydraulic
oil, please contact us for detailed
information and precautions.
mTake care that the permissible
voltage range is not exceeded.
,Turn on the AC solenoid after you
have installed the coil on the valve.
.Connect a drain pipe to the T(R)
port of the valve for operation
symbols 2X, H2X and E2X.
⁄0If the product is kept at the
switched position for a long time
at a high pressure, operation
failure may occur due to sticking of
fluid. When it must be kept at the
switched position for a long time
at a high pressure, contact us for
further information.
⁄1When you use a detent type valve
(E2X, E3X, E3Z), keep power turned
on in order to keep the switched
position without fail.
⁄2It should be noted that the manual
pin operating force is changed by
tank line back pressure.
⁄3If you use the valve with power
kept turned on, the coil surface
temperature will rise. So determine
the valve installation position to
ensure that your hand will not
touch the heated position.

Shock-less Type (Type symbol: F)
Switching response characteristics
Indicates the pressure waveform of valves in the
hydraulic circuit given in the following sketch.
In the dry type valve, a big impact (noise) or
pipe vibration will occur due to sudden pressure
drop or rise caused by open/close operation of
the valve. In the shock-less solenoid valve,
however, there is no pressure change due to
open/close operation of the valve. Accordingly,
there is no impact (noise) or pipe vibration when
the valve is switched.
