The KBDG4V-3-2C03F-Z-M1-PE7-H7-10 valve is produced by Vickers and belongs to the Directional Control Valves series. It regulates hydraulic flow and pressure for automated machinery, and it mates to manifolds through the ISO 4401-03 (ANSI D03) interface. A 24 VDC power supply energizes the onboard electronics. The control board accepts a ±10 VDC command signal that positions the spool proportionally. Movement begins when the input exceeds 0.25 V, allowing sensitive adjustments around the neutral point. A ±10 VDC spool position monitor outputs real-time feedback for closed-loop control systems. Solenoid drive uses 10 kHz pulse-width modulation and can draw up to 3 A during operation. A step change from zero to full command reaches steady state in 17 ms, delivering rapid response.
The valve passes 3 L/min at a 5 bar differential, which suits low-flow servo circuits. Its fine meter-in/meter-out metering profile keeps flow symmetrical when charging or exhausting an actuator. Pressure capacity reaches 350 bar on ports P, A, and B to handle high-pressure supply lines. Port T endures 105 bar so return pressures remain within safe limits. Closing from full stroke to neutral occurs in 16 ms for quick deceleration events. Electrical connections are made through a 7-pin plug, and a mating half is provided to simplify wiring. The housing meets IP65 and IP67, preventing dust ingress and temporary water immersion. There are no manual overrides, so commissioning and emergency operation rely exclusively on electrical commands.
