The KBHDG4V-3-5X-PC7-10 valve belongs to the Directional Control Valves series from Vickers and directs hydraulic flow in automated machinery. It runs from a 24 VDC power supply, and its 7-pin PC7 connector carries both power and control signals. Pin A supplies +24 VDC to the onboard electronics, while Pin C is intentionally left unconnected to simplify wiring checks. Continuous service is possible because the coil is rated for a 100 percent duty cycle and can draw up to 3 A when fully energized. A 0.25 V command threshold supports fine positioning, and hysteresis stays below one percent of the maximum stroke, maintaining repeatable flow rates during small input changes.
Ports P, A, and B tolerate pressures to 350 bar, allowing the valve to operate in high-pressure circuits. The body matches the ISO 4401-03 (D03) pattern and installs on a subplate, so replacements require no manifold modifications. An IP67 enclosure guards the assembly against dust and temporary water exposure, and pin F outputs a ±10 VDC monitor signal that reflects spool position for system diagnostics. Internal pulse-width modulation works at 10 kHz to reduce audible noise and heating. The spool travels from 0 to 100 percent in 17 ms and returns in 16 ms, supporting rapid direction changes in closed-loop hydraulic drives.
