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.
