The KBSDG4V396L24M1PE7H711 valve belongs to the Directional Control Valves series and is manufactured by Vickers for precise hydraulic automation. It operates from a 24 VDC supply so typical control cabinets can energize the onboard electronics without conversion. An analog command range of ±10 VDC positions the spool, while a 0.25 V threshold defines the minimum input that produces movement. The input stage offers 47 Ω impedance to prevent excessive loading on motion controllers, and it mirrors actual spool position through a ±10 VDC monitor output for supervisory checks. Up to 18 V of common-mode voltage can be tolerated, protecting the differential amplifier against ground shifts. A 10 Ω output impedance matches the driver to the proportional solenoid for stable current control. Wiring is completed through a 7-pin PE7 plug, and the body mates to an ISO 4401-03 (D03) subplate to streamline manifold installation.
Ports P, A, and B carry a pressure rating of 350 bar so the valve can regulate high-pressure servo circuits. The solenoid is specified for a continuous 100 percent duty cycle, allowing uninterrupted modulation during extended machine cycles. A maximum supply current of 3 A defines the capacity needed from the power source. Internal circuitry keeps the differential between terminals d and e below 100 mV, minimizing offset and drift. A pulse-width-modulation carrier set at 10 kHz drives the coil, reducing hysteresis and limiting audible noise. Dynamic behavior is characterized by a 17 ms step response from 0 to 100 percent command and a 16 ms recovery from 100 to 0 percent, enabling rapid directional changes in closed-loop hydraulic systems.
