    The power amplifier and pressure sensor

    are integrated in the control valve.

    Furthermore, the closed-loop control design

    EHDFG-04 and 06: The spool displacement is shown as a

    percentage.    both pressure control valves and directional control valves.

    Open-loop types are also available.

    EHDFG-04 and 06: ±24V DC power supply is needed.

    EHDFG-01, 03, 04 and 06: 0 to ±5V DC command signal

    is needed.

    The trouble, if arises, can be easily detected by

    monitoring the dispatch of the alarm signal with

    sequence controller or computer.

    greatly improves the linearity, hysteresis and

    stability in control pressure.

    Control pressure can be shown digitally on

    the optional pressure display panel .

    Why convenient ?

    Pressure can be displayed remotely with the

    Yuken's digital panel metre or any indicators

    obtainable in the market and also can be

    transmitted into a computer.

    If any trouble arises in the system and the

    command signal does not match to the output, the

    alarm signal is dispatched.

    5

    Analog voltages can be output by using the

    incorporated sensor for monitoring pressure, etc.

    .    The sensor in directional control valves is to monitor the

    spool position. Valves without sensor are also available in
