Installation and mounting space can be minimized.
No special skill is required for assembly. Any addition/alteration to the hydraulic circuit can be made quickly and
easily.
Problems such as oil-leaks, vibration and noise which may be caused by piping are minimized, increasing the
reliability of the hydraulic system.
Maintenance and system check-ups can be easily carried out as they are normally installed in stackable units.
Note: Solenoid operated directional valve is included in
the number of stack
Mounting surface dimensions confirm to ISO
4401 (Hydraulic fluid power four port
directional control valves mounting surfaces)
as listed in the table below.

Any type of hydraulic fluid. Listed in the table below can be used.
Note: For use with hydraulic fluids other than those listed above, please consult for YUKEN representatives in advance.
Always be sure to use hydraulic fluids within the stipulated conditions shown below.
Viscosity: 15 to 400 cSt, Temperature : -15 to +70° C.
Due caution must be given for maintaining control over contamination of the hydraulic fluids which may
other wise lead to breakdowns and shorten the life of the valve. Please maintain the degree of contamination
within NAS 1638-Grade 12. Use 20 µm or finer line nominal filter.
Petroleum base oil Use fluids equivalent to ISO VG 32 or VG 46.
Synthetic fluids
Use phosphate ester or polyol ester fluid. When phosphate ester fluid is to be used, prefix “F-” to
the model number because a special seal (fluororubber) will be used.
Water containing fluids Use water-glycol fluid

MODULAR VALVES
474
The selection of a modular valves, to suit a particular function or hydraulic circuit are made in exactly the
same way as conventional valves, taking into account the flow and pressure of each valve to be used. In
some cases, the stacking system may be restricted, so please refer to the following instructions for stacking
sequence. Please note that, when designing a system using modular stacking valves, due consideration
should be given to working space for future maintenance.
Because reducing valves are spool type, there is an
internal leakage. In the stacking sequence shown in the
drawing left (incorrect), the cylinder moves due to
leakage through the pilot pressure line .
Consequently, retaining the position of the cylinder
using a pilot operated check valve becomes impossible.
The stacking sequence shown in the drawing right
(correct) is required in order to retain the cylinder
position.
In B to T flow in the drawing left (incorrect), pressure is
generated at part with a throttle effect of the throttle
and check modular valve. Depending upon the pressure
so generated, the reducing modular valve may perform a
pressure reducing function which causes a shortage of
output power from the cylinder and spoils the smooth
operation of the cylinder. Therefore, stacking sequence
in the drawing right (correct) is required in this
combination.
In A to T flow in the drawing left (incorrect), pressure
is generated at part with a throttle effect of the
throttle and check modular valves.
The pressure so generated acts to shut the pilot
operated check modular valve and eventually creates
an open and shut operation of the valve repeatedly
which may cause the cylinder to have a knocking
effect (the same effect will occur in the case of B to T
flow). Therefore. The stacking sequence in the
drawing right (correct) is required in this combination.

When mounting the modular valves, use base plates and
sub-plates specified below. If these base plates and the sub-
plates are not used, ensure that the mounting surface has a
good machined finish.
* For the details of sub plates see the solenoid operated
direction control catalogue No. EIC-E-1002 Page No. 370.
Assembly should be carried out in clean conditions and in
accordance with the following procedure. Caution/attention
should be paid to ensure that the interface of the valves are
clean and free from dirt or other foreign materials.
1) Screw in the four stud bolts, fully into the tapped holes
on the mounting surface of the specified base plate, sub-
plate or manifold.
2) Stack the modular valves and solenoid operated directional
valves in accordance with the hydraulic circuit, place the
O-ring inserted face on the base plate and make sure that
the port arrangement of the modular valves are in the .
correct position before stacking the valves using stud bolts.
3) Align both the end of the valves stacked.
4) Screw-in the four nuts onto the stud bolts and tighten with
the specified torque. After the test run, be sure to re-tighten
the nuts to a firm tightness within the specified torque.
Modular valves are mounted using stud
bolts which are supplied in a kit form.
When mounting, see the following table
for tightening torque. After the test run, be
sure to tighten again to a firm tightness
within the specified torque.
Pressure drop curves of the modular valves are those
based on viscosity of 35cSt and specific gravity of 0.850.
when using the modular valves in condition other than
the above mentioned, find the appropriate valves
referring to the following table and formula

Min. adjustment pressure varies with tank line back pressure and may be obtained from the following formula.
Min. adjustment pressure = Min. adjustment pressure value + Tank line back pressure.
Add T-Line pressure drop value of the valve to be stacked on the base plate side to the tank line back pressure.
To make pressure adjustment, loosen the lock nut and turn the pressure adjustment screw clockwise or anti-
clockwise. Be sure to re-tighten the lock nut firmly after making adjustment to the pressure.
In case of a small flow, the setting pressure may become unstable. To avoid this, refer to the minimum flow
characteristic curve of the previous page and use the valve within a range as shown with .

Valves are mounted with four stud bolts. Valve
combination varies according to the circuit type.
Hence, the mounting bolt kits are available on a
combination type basis.
When ordering the mounting bolt kit, be sure to give
the bolt kit model number from the table below.
