Pump Type
These AR series pumps have been developed on the basis of
the same design concept as A series pumps which are
renowned for high efficiency and low noise level.
Using an alminum body, the size of the pump is more compact
and the mass is considerably reduced. The noise level has
also been reduced.

■Noise Level
These pumps have been developed especially for low noise
operation. To comply with a wide range of applications
including the injection moulding machines, PV2R Series
pumps provide a wide range of output flows, from 5.8 to
237cm3/rev.
PV2R Series Vane Pumps
The PV11R Series pumps are durable up to pressures as high
as 40 MPa. The problem of excessive wear to the vanes and
cam ring, which usually occurs in such high pressure vane
pumps, has been resolved through special methods in both
mechanical construction and lubrication systems.

These valves control the reciprocating and rotating speed of
hydraulic actuators, A variety of flow control valves including
pressure and/or temperature-compensated flow control valves
are available.
These valves are pressure and temperature compensating
type valves and maintain a constant flow rate independent of
changes in system pressure (load) and temperature (viscosity
of the fluid). These features allow them to control the speed of
the actuator precisely. The valves with an integral check valve
allow a controlled flow and reverse free flow. Repeated
resetting can be made easily with a digital readout.

WIDE RANGE OF MODELSChoose the optimum valve from a large selection to meetyour needs.
The following is our full range of solenoid operated
directional valves and solenoid controlled pilot
operated directional valves.
Solenoid Operated Directional Valves / Solenoid Controlled Pilot Operated Directional Valves
Shockless type proportional and flow control valves have been developed by employing the basic design concept of
“G”series solenoid operated directional valves.
The maximum speed of actuators can be controlled optionally as the shockless type directional and flow control
valves have maximum flow rate adjustment functions, features which are not available on the "G" series solenoid
operated directional valves.
The power amplifiers for use with the shockless type directional and flow control valves have digital setting systems
allowing for excellent operational maneuverability and repeatability. They offer two types of slop mode ;“SLOPE
CONSTANT”and“TIME CONSTANT”, and nine different types of shockless curves (one straight line slope and
eight waveforms). The optimum setting can be selected to suit any load condition.

●Your valuable machines are protected from vibration and shocks
■Shocks caused by acceleration and deceleration are reduced.
■Oil hammering during spool shifting is reduced.
■Relationships between SOL signals and flow patterns
The G series solenoid operated directional valve reduces any
shocks that may arise when starting machinery or shifting the
spool.
These valves feature less pipe leakage and offer more
accurate control and improve the reliability of the machinery
on which they are used.

Modular ValvesModular ValvesYUKEN MODULAR VALVES are designed to simplify
hydraulic systems, to eliminate the use of pipe connections
and to save space, time and costs. The modular valves have
standardized interfaces (ISO 4401, CETOP, NFPA) and
thickness in accordance with each valve size. Any hydraulic
circuit can be created by stacking the modular valves in the
correct sequence one upon another and bolting the various
stacks to a common manifold base.
●Modular valves remarkably minimize the installation area
and space.
●No expert skill is required to assemble. Changes or
additions to the circuit can be easily and quickly carried out.
●Problems such as oil leaks, vibration and noise which may
arise from pipes and tubes are minimized because pipes
and tubes are not necessary.
●The simple installation method of modular valves allows for
easy maintenance.

The EH Series on-board electronic proportional controls are compoundelectro-hydraulic products which merge the latest electronic and sensortechnology with Yuken's reputable E Series proportional controls. Yuken hasrealized an industry leading position by creating compact hydraulicequipment that features high precision and reliability by unifying the amplifier,and sensor, all of which are required for proportional or servo controlsystems.
Series Proportional Electro-Hydraulic Control Valves
●Proportional control systems or servo systems can be easily structured by simplypreparing the power source (DC) for controls and command signals along with thehydraulic source.Amplifiers exclusively used for the system or separately installed control panelsare unnecessary.
●By using built-in sensors;(1)pressure and orifice openness, which can be converted to flow rate, can be
detected and controlled remotely.(2)along with a compound amplifier, a closed loop system can be structured.(3)sensor output signals or deviation signals at structuring closed loop system can
be monitored.●Disadvantages seen in ordinary hydraulic systems in which hydraulic components,sensors and amplifiers are interconnected with each other but installed separatelyare eliminated.

High-speed linear servo valves have outstanding features of
high response and exceptional contamination resistance.
These features are achieved by the compact and powerful
linear motor which directly drives the spool and gives electric
feedback of the spool position. These valves have garnered
an excellent reputation since their launch by Yuken in 2001.
High-speed Linear Servo Valves/Servo Amplifiers
On-board electronics type linear servo valves have been
developed based on high-speed linear servo valves, but with a
focus on downsizing the pilot valve. The integration of the
exclusive amplifier and the linear servo valve create a high

Energy-Saving Hydraulic Units and ControllersEnergy-Saving Hydraulic Units and Controllers
Hydraulic units equipped with variable displacement pumps
feature greater energy-saving than those with f ixed
displacement pumps.
Yuken's energy-saving hydraulic units and controllers utilize
rotational frequency control with an inverter. This innovative
configuration solves the problem of efficiency losses suffered
by induction motors operating at light loads and ensures
significant energy savings.
Energy-saving effects can be achieved by adding the controller, the pressure sensor, and the inverter to an existing
unit and carrying out simple adjustments.

Energy Consumption : 1/10 compared to the standard hydraulic systemThe IH (intelligent hydraulic) servo drive pack is a compact energy - saving and low - noise hydraulic device which is
combined as one with the AC servo motor, piston pump, reservoir and hydraulic control circuit. This combination can
control the number of revolutions of the servo motor and adjust the discharge and pressure of the pump. This device
can be combined with the sensor - equipped cylinder and dedicated controller to facilitate the configuration of a
position, speed and pressure control system.
The IH Servo Drive Pack pump is a bidirectional revolution pistonpump which offers high performance in a wide range of very low tohigh revolutions. The hydraulic control circuit simply consists ofsafety valves and self priming valve, without a control valve in thepump discharge line and the series line between cylinders. Thereservoir is made compact by using space around the pump. Withthe oil supply port of hydraulic fluid doubling as an air breather andthe side-mounted oil level gauge, the pump is well equipped as ahydraulic driving force.
Intelligent Hydraulic Servo Drive Pack <AC Servo Motor Driven Hydraulic Pump Control System>
●Power consumption is reduced by 10 % (compared to Yuken's YP pack), moreover, the oil temperature rise is
minimal.
By Yuken's own comparison, the YF-Pack consumes 10% less power when compared to conventional hydraulic
power units. Because of its increased cooling capacity, the YF-Pack radiates less heat to other machines and
restrains their surface temperatures to a low level. This advantage results in a temperature rise of less than the
ambient temperature plus 12 degrees centigrade.
●Installation space is reduced to 1/2 (compared to YP pack)
Volumetric ratio : 50% reduction
Mass : 30% reduction
●Low Noise & Low Vibration
Developed to restrain vibration, YF-Pack hydraulic power units of cubic design operate with very little noise and low
vibration.
