    D05/NG10 (Standard Control) Proportional Valves

    D05/NG10 (Standard Control) Proportional Valves

    KBD/TG4V-5, 1* Series - Pressures to 315 bar (4500 psi)

    VickersTM KB*G4V-5 proportional valves are designed to provide controlled oil flow in proportion to an electrical command signal. They are available in two versions. Firstly a double solenoid version that will provide reversible flow and return to an actuator. Secondly a single solenoid version that provides a single direction of flow.

    The KB valve incorporates an integral control amplifier. Factory set adjustments for gain, spool deadband compensation and dither ensure excellent reproducibility valve-to-valve.

    Electrical connection is via a standard 7-pin plug and requires a power supply and command signal which can be either voltage or current (model code option). In addition to improving machine performance and life, the KB proportional valves substantially simplify system design by combining direction and flow capabilities in one single package that mounts onto a standard ISO 4401 interface.

    New Features and Benefits

    K(A)D/TG4V-5, 3* Series - Pressures to 315 bar (4500 psi)

    Vickers K(A)D/TG4V-5 proportional valves are designed to provide a controlled oil flow in proportion to a command signal. They are available in two types, firstly a double solenoid version that will provide reversible flow and return to an actuator, and secondly a single solenoid version that provides a single direction of flow. Hydrostats are available for load compensation and if flow enhancement is required for the single solenoid version, parallel flow path modules are available that will boost the flow capacity to nearly twice that of the standard valve.

    Features and Benefits

    • Wide range of spool and flow rate options
    • Supported by amplifiers and auxiliary function modules from the Vickers range
    • Electronic feedback LVDT ensures accurate speed control
    • Current feedback provides inherent protection from electrical interference
    • Vibration and shock tested

    Proportional Directional Control Valves Two-Stage Models Without Electrical Feedback


    KBDG5V-5-1* Series - Pressures to 315 bar (4500 psi)

    VickersTM KBDG5V-5/7/8/10 are solenoid operated directional control, non-feedback type proportional valves.

    These are two-stage proportional directional control valves in which the main-stage spool is positioned according to the output from an integrally mounted proportional, solenoidoperated, pressure-reducing valve. Direction of main-spool travel depends upon which of the two solenoids of the pilot valve is energized and the amount of travel is dependent upon the current input to the solenoid.

    At any intermediate position of the main spool, a force balance exists between the controlled, reduced pilot pressure acting on the spool end and the opposing centering spring, plus the action of flow forces. There is no electrical feedback of the main-stage spool position.

    This range of valves offers effective and economic solutions for applications having repetitive load conditions throughout each operating cycle, e.g. mold closure /opening in plastics molding machinery.

    Features and Benefits

    • These global products, manufactured to world-class quality standards, are sold and serviced throughout the world.
    • These valves open up expanded application opportunities as a cost effective alternative to feedback-type proportional and servo valves.
    • Auxiliary DIN-rail mounted function modules available.
