    D10/NG32 (Servo Control) Proportional Valves

    Proportional Two-Stage Directional Valves Servo Performance with Double Spool Feedback

    KBHDG5V-10 Series

    Pressures to 350 bar (5000 psi)

    General description

    Eaton proportional valves shown in this catalog are suitable for working pressures up to 350 bar (5000 psi) and flow rates to 720 l/min (190 USgpm). They are designed to provide a controlled oil flow in proportion to a command signal, with spool position feedback to provide accurate control. Zero lapped spools are available for closed loop control applications and hydrostats are available for load compensation.

    KBHDG5V-5/7/8/10

    A range of proportional directional valves with control amplifiers built directly on, and prewired to the valves. Factory-set adjustments of gain, spool deadband compensation, and offset ensure high valve-to-valve reproducibility. The only electrical inputs required are power supply (24V) and a voltage command signal of ±10V . The amplifier is housed in a robust metal enclosure, sealed against ingress of water and other fluids. Electrical connections are via a standard 7-pin plug. A spool position monitor point allows the function of the valve to be electrically monitored . Ramp functions, if required, can be generated externally.
