Hydraulic Fluids
Fluid Types
Any type of hydraulic fluids listed in the table below can be used.
Petroleum base oils
Use fluids equivalent to ISO VG 32 or VG 46.
Synthetic fluids
Use phosphate ester or polyol ester fluid. When phosphate ester fluid is used,
prefix "F-" to the model number because the special seals (fluororubber) are required to be used.
Water containing fluids
Use water-glycol fluid.
Note: For use with hydraulic fluids other than those listed above, please consult your Yuken representatives in advance.
Recommended Fluid Viscosity and Temperature
Use under conditions where the viscosity and temperature of the hydraulic fluid remain in the ranges indicated in the
following table.

If the valve is provided with a vent ristrictor (ex. : A-BSG-03), the viscosity range should be 15 - 200 mm2/s (80 - 900 SSU).
Control of Contamination
Due caution must be paid to maintaining control over contamination of the hydraulic fluids which may otherwise lead to
breakdowns and shorten the life of the valves. Please maintain the degree of contamination within NAS 1638-Grade 12.
Use 25 µm or finer line filter.

Instructions
To adjust the pressure, loosen the lock nut and turn the handle slowly clockwise for higher
pressures or anti-clockwise for lower pressures. After adjustments, do not forget to tighten
the lock nut.
Piping of the tank line should not be connected to any tank line of the other valves, but
connected directly to the reservoir.
Pressure is limited by collars fitted. If a working pressure cannot be attained,
remove some collars. One collar is equivalent to 10 MPa (1450 PSI).
If the internal volume of the vent line is too large, chattering is likely to occur.

Instructions
If a remote control relief valve is used in the vent circuit, see page 203. In addition, if the internal volume of the vent
line is too large, chattering is likely to occur. Thus, as far as possible reduce the inside diametre and the length of the
pipe.
To adjust the pressure, loosen the lock nut and turn the handle slowly clockwise for higher pressures or anti-clockwise for lower pressures. After adjustments, do not forget to tighten the lock nut.
Piping of the tank line should not be connected to any tank line of the other valves, but connected directly to the
reservoir.
Pressure is limited by collars fitted. If a working pressure cannot be attained, remove some collars. One collar is
equivalent to 10 MPa (1450 PSI).
With a small flow, the setting pressure may be unstable. Use models numbered 03 and 06 with a flow rate above
8 L/min (2.1 U.S. GPM) and model 10 with 15 L/min (4.0 U.S. GPM).

Pilot operated relief valves here have been particularly developed as low-noise types. Able to protect pumps and control
valves against excessive pressures, they are used to control the pressure in the hydraulic system to a constant level.
Remote control and unloading are permitted by using vent circuits.

These valves are a combination of a pilot operated relief valve and a solenoid operated
directional valve. Piping between the two is eliminated as the solenoid valve is directly
mounted on the relief valve and connected with the relief valve vent. Pump pressure
may be unloaded remotely by an electrical signal to the solenoid, or by connecting pilot
relief valves to the solenoid valve ports.

Models with vent restrictor are applicable only for the vent type 2B3A and 2B3B. For details, see page 222.
Use high venting pressure types to reduce response time from unloading to onloading.
For the details of the vent types, see the following page.
The coil codes are the same as for solenoid operated directional valve DSG-01. See the Solenoid Ratings on page 345.
The coil type numbers in the shaded column are handled as optional extras.
In case these coils are required to be chosen, please confirm the time of
delivery with us before ordering.

Models with vent restrictor
The type with a vent restrictor has a vent restrictor in vent types 2B3A and 2B3B added between a relief valve and
a solenoid operated directional valve. If prevents shock to the main circuit by gradually lowering the venting pressure
in the shift from the set pressure to unloading.
Unloading pressure are the same as without a vent restrictor.

The low-noise solenoid controlled relief valve is a combination of a low-noise type pilot operated relief valve and a
solenoid operated directional valve. It is used for no-load pump operation by using electric signals or, together with a
remote control relief valve, for two or three pressure control of the hydraulic system.

1. Models with vent restrictor are applicable only for the vent type 2B3A and 2B3B. For details, see page 231.
2. Use high venting pressure types to reduce response time from unloading to onloading.
3. The vent types are the same as for the conventional type solenoid controlled relief valves. For the details of the vent types, see page 221.
4. The coil codes are the same as for solenoid operated directional valve DSG-01 valve. See the solenoid ratings on page 345.
The coil type numbers in the shaded column are handled as optional extras.
In case these coils are required to be chosen, please confirm the time of
delivery with us before ordering.

Models with vent restrictor
The type with a vent restrictor has a vent restrictor in vent types 2B3A and 2B3B added between a relief valve and a
solenoid operated directional valve. It prevents shock to the main circuit by gradually lowering the venting pressure
in the shift from the setting pressure to unloading.
Unloading pressures are the same as without a vent restrictor.

Remarks
PRESSURE CONTROLS
H/HC Type Pressure Control Valves
These valves are hydraulically damped, direct operated, pressure control valves which can be actuated by internal or
external pilot pressure.
HC Type Pressure Control Valves
There are various types of valve including sequence,
unloading and low pressure relief valves, all of which
are operated by a pressure rise in the circuit, sensed
either internally or remotely.
They are available with integral check valves for use
when free reverse flow from secondary port to the
primary port is desired. There are various types of
valve including sequence and counterbalance valves, all
of which are operated by a pressure rise in the circuit,
sensed either internally or remotely.

1. For the details of valve types, see the following page.
2. Type 1 is only possible for pressure adjustment ranges L and M.
3. Models with auxiliary pilots are used where valves must be operated under a lower external pilot pressure than the adjusted pressure (types N, A,
and B: about 1/8 of adjusted pressure; type C: about 1/16). This does not apply to pressure adjustment ranges L and M and valve type 1.
Instructions
To adjust the pressure, loosen the lock nut and turn the pressure adjustment screw slowly clockwise to increase pressures
or anti-clockwise to decrease pressures. After adjustments, do not forget to tighten the lock nut.
Connect the secondary side pressure ports of types 1 and 4 (internal drain) and the drain ports of types 2 and 3 (external
drain) directly to the reservoir with a back pressure close to the atmospheric pressure.
There are two threaded connection primary pressure ports. They can be connected each other in-line; one as inlet and
the other as an outlet or the valve can be used by plugging one of the pressure ports.

Can be used as lowpressure relief valve, but
be careful to occurrence of
surge pressure.
Used to control the
operational sequence of two
or more actuators. If
primary pressure exceeds
the pressure setting,
effective fluid is delivered
to the secondary side.
Used for the same
purpose as for the type 2.
Operated by external pilot
pressure irrespective of
primary pressure.
Used as unloading valve.
If external pilot pressure
exceeds the pressure
setting, the pump is turned
no-load by releasing all
fluid to the tank.

PRESSURE CONTROLS
Pressure Reducing Valves / Pressure Reducing and Check Valves
Pressure reducing valves are used to set the pressure of a hydraulic circuit below that of the main circuit. In addition,
operation under remote control is possible by using the remote control port. Pressure reducing and check valves have
check valves, which allow a free flow from the secondary side to the primary.

Sub-plates are available. Specify the sub-plate model number from the table above. When sub-plates are not used, the mounting
surface should have a good machined finish.
The sub-plates are the same as those for H type pressure control valves. With the reducing and check valve, the sub-plate is used in a
position 180° turned (upside down) from the normal position. When mounting the sub-plate, be sure to bring the valve locating pin to
the sub-plate pin hole. For dimensions, see page 244 to 246.
Instructions
To adjust the pressure, loosen the lock nut and turn the pressure adjustment handle slowly clockwise for higher
pressures and anti-clockwise for lower pressures. After adjustments, do not forget to tighten the lock nut.
Connect the drain port directly to the reservoir in which case the pressure at the drain port should be kept at a low
back pressure close to the atmospheric pressure.
In case of "Threaded Connections", there are two threaded connection type primary pressure ports. They can be
connected each other in-line; one as an inlet and the other as an outlet or the valve can be used by plugging one of the
pressure ports.

To use remote control relief valve in the venting circuit, see page 203. If the internal volume of the vent line is too
large, chattering is likely to occur. Thus, as far as possible reduce the inside diametre and the length of the pipe.

PRESSURE CONTROLS
These valves are used to operate the pumps with minimum load in
accumulator circuits or in high-low pump circuits.
In accumulator circuits, when the system pressure reaches to a cut out
pressure (adjusted maximum), the valve acts to divert the pump
delivery to the reservoir at low pressure, thus the pump is unloaded
automatically.
When the accumulator pressure drops to the cut in pressure (refer to
characteristic chart on page 269), the valve directs the pump delivery
to the accumulator and hydraulic system.
An integral check valve prevents reverse flow through the valve from
the accumulator.
In high-low pump circuits, the valve acts to unload the large volume
pump with the same manner as described above during load operation
of the small volume pump.

Pilot-drain system
A pilot-drain system is typically configured with an external pilot and an external drain, as
indicated by the right graphic symbol. However, customized pilot-drain systems with an internal
pilot are also available.
For the internal pilot type, the design standard number at the end of the model number is uniquely
assigned. Refer to the table below for the internal pilot type. Please contact us for details.

pressures or anti-clockwise for lower pressures. After adjustments, do not forget to tighten the lock nut.
Take care not to neglect connecting the drain pipe to the reservoir; otherwise not only will the valve fail to operate
properly but also the line pressure will rise infinitely. Extend the end of the drain pipe into fluid.
Limit the pressure drop between the valve and the accumulator in an accumulator circuit below 10% of the cut-out
pressure.
Limit the drain port back pressure below 2% of the cut-out pressure.

These pressure switches have built-in electronic circuit on a semiconductor
pressure sensor and an open collector insulated by a photocoupler has been
used as output. As the use of semiconductor has put movable parts away from
the sensor section, high reliability and durability can be obtained.
These pressure switches are suitable for the applications not only compact,
light weight and vibration-proof are required but also better substitute to
conventional pressure switches.

The pressure monitoring system is for watching hydraulic system pressure
and is composed of highly reliable pressure sensor (SJT*-02-10) and
easy-to-use digital pressure monitor (DP*-*-*-10). There is no specific
model number code for the pressure monitoring system itself, therefore,
when ordering, specify the digital pressure monitor and pressure sensor
with respective model number code.
Remote pressure indication
Even if the monitor is located away from the unit, remote pressure
indication can be obtained by combination with special sensors.
Remote-setting pressure sensors
The pressure sensor can be used as a pressure switch with two
contacts: top and bottom. Pressure can be set and checked without
using any other pressure gauge, moreover, such pressure setting and
pressure check can be made when no pressure is applied in the
hydraulic system.
Digital Pressure Monitors
The digital pressure monitor indicates the system pressure and also
despatches signals when the system pressure reaches to the preset
pressure. The monitor can be separated from the sensor and installed
away from the sensor. The monitor and the sensor so separately installed
can be connected by wire, therefore, a long hydraulic piping is not
required. The digital pressure monitor provides high accuracy when it is
used with a special pressure sensor (SJT*-02-10).
