0.2 to 14MPa
Features
qWhen the pressure in part of the
circuit is lower than the main circuit,
this modular valve controls pres-
sure by switching the low pressure
to secondary pressure (high pres-
sure, low pressure).
wEven when pressure changes in the
primary main circuit, the reduced
secondary pressure is maintained
at a constant level.

zSee the Pressure-Flow Rate
Characteristics for information about
how the flow rate is controlled at low
pressures.
xNote that a change in tank port back
pressure causes a change in setting
pressure.
cInstability occurs when there is a
small setting pressure differential
between the high pressure and low
pressure, so be sure to maintain at
least the minimum pressure differen-
tials described below.
C Type:
At least 0.3MPa {3.1 kgf/cm

}
1, 2 Type:
At least 0.5MPa {5.1 kgf/cm

}
vVent piping is not possible.
bNote that a sub plate and installation
bolts are not included. See pages D-
90 through D-95 if these items are
required.
nLow pressure is attained when the
solenoid is on.
mThe coil surface temperature
increases if this pump is kept contin-
uously energized. Install the valve so
there is no chance of it being
touched directly by hand.
