DIRECTIONAL VALVES – HYDRAULICALLY OPERATED SPOOL

    HD-WH SERIES

    HUADE LOGO

    The Huade HD-WH series is a hydraulically operated spool directional valve, in which the spool is shifted by the pressure of an external pilot circuit rather than by solenoids or manual levers. This valve type is the solution for circuits where directional control must be integrated into a hydraulic or pneumatic logic without depending on electrical supply.

    Benefits

    • Purely hydraulic actuation with no electrical components required
    • Integration in mixed hydraulic/pneumatic systems through control cylinders operable by pneumatic pressure
    • Triple spool return mode (spring, without spring and detent) allows the valve behaviour to be adapted to system requirements
    • Simplified circuit architecture in complex systems with no electrical interface required

    Application fields

    • Circuits with purely hydraulic sequence logic
    • Machinery with remote piloting via auxiliary circuit
    • Mixed hydraulic/pneumatic systems
    • Offshore applications and environments with electrical restrictions
