The KBFDG4V32C20N10ZM1PC7H711 valve belongs to the Directional Control Valves series from Vickers and regulates flow in automated hydraulic circuits. It bolts to an ISO 4401-03 (ANSI/B93.7M-D03) interface and meters 20 L/min through the a port and 10 L/min through the b port for controlled actuator movement. A maximum working pressure of 350 bar (5000 psi) supports high-pressure machinery. The on-board electronics operate from a 24 V DC supply and can draw up to 3 A when fully energized. Spool position is commanded with a ±10 V DC signal, and the element begins to shift once the input exceeds a 0.25 V threshold, allowing precise proportional control.
Dynamic response is defined by a 17 ms 0–100 % step time, while current is modulated at a 10 kHz PWM frequency to maintain stable flow. The unit returns a ±10 V DC monitor signal so the controller can track spool position. A 7-pin PC7 connector carries power and signals, and the enclosure is sealed to IP65/IP67 for protection against dust and water. The design omits manual overrides, ensuring that all movements remain electrically driven. Continuous operation is permitted with ambient air and hydraulic oil temperatures up to 70 °C, accommodating heat generated by nearby power units.
