KBSDG4V396L24PE7H710

The KBSDG4V396L24PE7H710 directional control valve is produced by Vickers within the Directional Control Valves series. It modulates flow paths in hydraulic automation systems based on an electrical input. The onboard electronics accept a ±10 V DC command signal so proportional spool positioning can be driven from standard control hardware. A matching ±10 V DC monitor output on pin F provides feedback of full stroke to simplify closed-loop tuning. The valve operates from a supply voltage between 21 V DC and 36 V DC and draws no more than 3 A, allowing direct connection to common industrial power supplies. Internal amplification uses a 10 kHz PWM carrier and supports a 100 percent relative duty cycle, ensuring continuous modulation without thermal cycling. Flow hysteresis across ports P, A, B, and T remains below 1 percent of maximum stroke, which helps maintain repeatable positioning under small signal changes. The sub-plate meets the ISO 4401-03-02-0-05 mounting interface for straightforward installation on manifold blocks.

The hydraulic sections withstand pressures up to 350 bar at ports P, A, and B, enabling use in high-load actuators; this capacity aligns with many industrial pump systems and avoids the need for additional pressure stages. Oil temperature can range from 0 °C to 70 °C during service, while cold start is permitted down to −20 °C, so the valve performs reliably in moderate climates; keeping fluid within this band prevents viscosity shifts that could slow spool movement. An enclosure rating of IP65 and IP67 shields the electronics from dust, water jets, and temporary immersion when mating connectors are engaged. Dynamic behavior is characterized by a 17 ms step response for a 0–100 percent change and 16 ms for a 100–0 percent change, enabling quick reversals in servo applications. Together, these pressure, temperature, sealing, and response specifications make the KBSDG4V396L24PE7H710 suitable for demanding, fast-acting hydraulic circuits.
