    Benefits

    • Closed-loop control automatically compensates for friction and temperature variations
    • Reduced pressure/command characteristic curve scatter compared to the external electronics version, thanks to integrated OBE closed-loop control
    • Precise dynamic response, adaptable to each phase of the cycle
    • Fewer components in the electrical cabinet thanks to electronics integrated directly in the valve body
    • The ZDBEE version with external pilot drain (port Y) allows pilot circuit separation from the main circuit
    • Independently adjustable rise and fall ramps via integrated potentiometers

    Application fields

    • Hydraulic presses with variable pressure cycles
    • Plastics and rubber processing machinery
    • Machine tools with precise working pressure control
    • Metallurgical and steel plants
    • Test benches and hydraulic power units
