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.

Flow Control ValvesFlow Control Valves

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.

Servo ValvesServo Valves

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

performance valve in a compact package which greatly

improves user-friendliness.

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-saving control system for hydraulic units (Energy saving controller)

■System Configuration ■Example of Reduction Rate of Power Consumption (Machining line for auto parts)

■Specifications

●Substantial energy saving of hydraulic units has been achieved by the inverter drive.

Extensive energy saving is possible by detecting a load

pressure with the pressure sensor and keeping the motor

rotation at the optimum level required for pressure holding.

Based on the concept above, the following three different

types of inverter-driven system and packages have been

developed.

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.
