    Features

    Specifications

    qVery long lifeThe movable iron core of the wet type sole-noid is immersed in oil, which keeps it lubri-cated and cushions it from impact and vibra-tion, ensuring very long life.

    wLow switching noiseThe wet-type solenoid valve provides verylow core switching noise, for quiet operation.

    eHigh pressure, large capacity, with minimalpressure lossComprehensive fluid reaction force compen-

    sation and low pressure compensation con-struction provide large capacity and lowpressure loss. G01 : 35MPa{357kgf/cm2}100r/minG03 : 35MPa{357kgf/cm2}160r/min

    rEasy connectionsA special wiring box provides a COM portand indicator light as standard for simplewiring and maintenance.

    tEasy coil replacementA plug-in type coil enables one-touch coil

    replacement. yWide-ranging backward compatibility makes

    it simple to replace previous valve modelswith this one. Combining this valve with amodular valve contributes to the compactconfiguration of the overall device.

    uGlobal support (G01 size)Meets overseas safety standards (CE, UL,and CSA). It can be safely used anywhere inthe world. Contact your agent for certifiedproducts.

    Note) The maximum flow rate of each valve depends on the pressure. For details, see pages S-9 and S-10.

    Note) 1. Maximum operating pressure depends on the valve type. For details, see page S-1. 2. For mounting bolts, use 12T or equivalent.

    zPipe system so that tank line isalways filled with oil.

    xSurge pressure should be keptbelow maximum tank line backpressure rating.

    cWhen using a 4-way valve as a 2-way or 3-way and blocking unusedports lowers the maximum flow.

    vKeep hydraulic oil clean. (Degree ofcontamination: NAS grade 12 orbetter). When petroleum hydaulicoil is used, it should conform to ISOVG32, 46.

    bDo not exceed permissible voltagerange of the coil used.

    nDo not supply electric power to theAC solenoid unless the coil ismounted to the valve.

    mProvide drain piping from the Tport, when valve spool types areA2X, H2X, E2X.

    ,If the changeover position is keptunder high pressure for an extend-ed period, malfunctions may occurdue to hydraulic lock. Please con-sult us when you have such appli-cation.

    .When the detent-type (E2X, E3X,E3Z) is used, we recommend thatthe electric power supply be contin-

    uous in order that the changeoverposition may be firmly maintained.

    0Resistance force against the manu-al override pin changes, dependingon the back pressure of the tankline.

    1Solenoid coil could be hot by con-tinuous operation. Do not touch thecoil directly by hand.
