■ Control Type
Control Type Graphic Symbols Performance Characteristics Explanation Page
"01"
Pressure
Compensator
Type
When the system pressure increases and comes close
to the preset cut-off pressure, the pump flow decreases
automatically while maintaining the set pressure as it
is.
31
"02"
Solenoid-two
Pressure
Control
Type
This type of control is ideal for an application where
the output power of the actuator has to be controlled
in two different load pressures while keeping the
actuator speed nearly constant.
53
"03"
Pressure
Compensator
with
Unloading
Type
It is suitable for a situation where a long unloading
time is required and heat generation and noise have
to be kept at their lowest levels.
•
The pump can be used in combination with the
multistage pressure control valve.
61
"04"
Proportional
Electro-
Hydraulic
Load
Sensing
Type
This is an energy-saving type control which regulates
the pump flow and load pressure to be at absolute
minimum necessary level to operate the actuator.
Pump flow rate and cut-off pressure are controlled
proportional to the input current to the control device
on the pump and the input current is regurated by the
specific amplifier.
62
"04E"
Electro-
Hydraulic
Proportional
Pressure &
Flow
Control
Type
This type of control has the pressure sensor and tilt
angle sensor in the pump. The pump is used with the
external amplifier (amplifier is integrated into pump
in case of "04EH").
Flow and pressure can be controlled in proportion to
input voltage by only one control valve.
The features has been greatly improved by electrical
feedback of swash plate tilt angle correspond to flow
rate and load pressure to control valve.
•
Linearity of input characteristics is excellent and
easy to set.
•
Hysteresis is lower, repeatability and reproducibility
are fine.

Control Type
by System
Pres.
This type of control is suitable for an application like
"Presses" where the changeover from rapid advance to
feed is required just when the pressing (pressurizing)
starts.

Two-Pressure
Two-Flow
Control Type
by Solenoid
Valve
This pump control is suitable for machining found
on machine tool, where machining starts after the
changeover from rapid advance, to feed has been
made.

Pilot Pressure
Control Type
Pressure
Compensator
The pump is used in combination with the pilot relief
valve or multistage pressure control valve. By
controlling the pilot pressure, the full cut-off pressure
can be remote-controlled according to your
requirements.

"09"
Constant
Power
Control Type
•
Pump input power can be controlled in accordance
with the motor output.
•
When the discharge pressure rise, the output flow
decreases corresponding to the preset input power.
•
The pump can act for function of two pumps, low-
pressure large-flow and high-pressure small-flow.
Therefore, the motor capacity can be reduced.
101
"00-
Z500"
Simple Two-
Pressure
Two-Flow
Control Type
•
This type of control enables one pump to act as two
pumps (low-pressure and large-flow/high-pressure
and small-flow-rate). Therefore, the motor capacity
can be reduced.
•
When the system pressure increases near the preset
“PL” pressure due to the load increase, the pump
flow automatically decreases to “QL.”
•
This type of control is suitable for an application
like the press, where switching from rapid
advance to feed is required just when the press
(pressurizing) starts.
•
The PH pressure can be remote-controlled with a
separately located relief valve. With this type of
control, it is easy to change the applied pressure
setting when materials or shapes of the press are
changed.

★1. Whenever setting pressure, make sure the full cut-off pressure never exceeds
the maximum intermittent pressure.
★2. Care should be taken in cases of used at a higher pressure than the rated
pressure, because operating terms may be restricted. For example, if used as
per maximum illustrated operating conditions, intermittent time at maximum
flow is restricted to under 1/5 of one cycle time and under six seconds
simultaneously. Conditions may vary according to the actual working pressure
and delivery (inclination angle of the swash plate). Consult factory or Yuken
sales representative for further information.
★3. Care should be taken in cases of used at a higher pressure than the rated
pressure, because operating terms may be restricted. For example, if used as
per maximum illustrated operating conditions, intermittent time at maximum
flow is restricted to under 1/5 of one cycle time and under six seconds
simultaneously. Conditions may vary according to the actual working pressure
and delivery (inclination angle of the swash plate). Consult factory or Yuken
sales representative for further information.
★1. The figures in brackets are for A22 type.
★2. As the specific gravities of water-glycol fluids and phosphate ester type fluids are higher than one, an overhead reservoir is required when pumps
are operated at 1400 r/min or more.
