The KBHDG4V38XPE710 directional valve belongs to the Directional Control Valves series and is manufactured by Vickers for hydraulic automation tasks where precise flow direction is required. It mounts on an ISO 4401-03 (D03) interface so it can be installed on standard size 03 subplates without adapter blocks. The onboard driver accepts a 24 V DC supply, aligning with typical machine power rails. Spool position is commanded either by a 4–20 mA current loop or a ±10 V DC voltage reference, allowing the valve to work with a wide range of analog controllers. All electrical terminations are made through a 7-pin PE7 plug that consolidates power, command, and feedback lines. Ports p, A, and B are rated for 350 bar so the unit handles high-pressure circuits used in industrial presses and injection equipment. Hysteresis is kept below 1 % of maximum stroke, which improves repeatability during small set-point changes. Coil drive is modulated at 10 kHz PWM to minimize audible noise and increase resolution.
Ingress protection is specified as IP67, giving the KBHDG4V38XPE710 enclosure resistance to dust and temporary immersion encountered in harsh plant environments. Reliable operation is maintained from −20 °C up to 70 °C ambient, covering cold start conditions and elevated cabinet temperatures. Dynamic performance supports rapid axis control: a ±90 % step settles in 25 ms, a full 0–100 % command reaches position in 17 ms, and a return from 100 % to 0 % completes in 16 ms. The electronic stage can draw as much as 3 A during transients, so upstream supplies must accommodate this peak. A monitor signal available on pin F provides a buffered ±10 V DC output that mirrors spool position for diagnostic or closed-loop feedback purposes.
