    High Frequency Hydraulic Check Valve Port Size 06 , 10 Standard Control Structure

    MA-DKZOR-T Hydraulic Proportional Direction Valve High Frequency MA-DHZO-T 06 and 10

    High performance hydraulic proportional valves
    with position transducer and positive
    spool overlap for best accuracy and
    dynamics in directional controls and not
    compensated flow regulations.
    They are specifically designed to achieve
    high speed closed loop controls and to
    implement alternated Pressure (Force)
    /Flow controls - options /S* coupled with
    spools ‘Q’ or ‘V’.
    The 4-way spool , sliding into a 5-chambers
    body , is directly operated by the
    proportional solenoid and it is controlled
    in closed loop position by means of
    the LVDT transducer feedback .
    The electronic driver supplies the proportional
    valve with proper current to align
    valve regulation to the reference signal,
    the integral execution has rugged construction
    and grants factory presetting for
    valve-to-valve interchangeability.
    Size: 06 and 10
    Max flow: up to 80 and 170 l/min
    Max pressure: 350 bar (DHZO)

    Above performance data refer to valves coupled with Atos electronic drivers, see section 2

    The flow regulated by the directional proportional valves is not pressure compensated. Thus it is affected by the load variations. To keep costant the regulated flow under different load conditions, modular pressure compensators are available (see tab. D150)

    For different P, the max flow is in accordance to the diagrams in sections 14.2 and 15.2

    0-100% step signal

    Competitive: The international advanced technology and process, the coil import from Germany, can replace Atos, Rexroth, Yuken and many other brand, the form and installation can completely interchangeable.

    Applications: Hydraulic system, marine, palstic machine and many other hydraulic systems and machines.

    We supply our valves to many OEM customers, the quality is the No.1 in China.
