The KBHDG4V35M1PE712 valve is manufactured by Vickers within the Directional Control Valves series and directs hydraulic flow in automation circuits by changing spool position according to an electrical command. The unit mounts on an ISO 4401-03 (NFPA D03) interface so it fits standard manifolds, and its spool rests with all ports closed in a zero-lap arrangement to hold actuators until a signal is applied. A ±10 V command input drives the onboard electronics, while motion begins once the 0.25 V threshold command voltage is reached. The connector also returns a ±10 V DC monitor signal that lets the controller verify actual spool position. Wiring is completed through a 7-pin connector with a PE7 plug for fast field replacement, and a 24 VDC power supply energizes the amplifier. Safe hydraulic limits are set at 350 bar on the P, A, and B ports and 105 bar on the T port.
For smooth flow control the driver modulates the solenoids at a 10 kHz PWM frequency, and step responses measure 17 ms from 0 to 100 percent and 16 ms from 100 to 0, enabling rapid directional changes in closed-loop systems. The housing carries an IP65/IP67 protection rating so it resists dust and water ingress when the mating connector is in place. System oil must meet ISO 17/15/12 cleanliness to protect the precision spool and reduce wear. A length of 237.236 mm and a height of 115.824 mm help the valve fit compact power units without blocking adjacent components, allowing designers to conserve space while maintaining reliable directional control in automated hydraulic machinery.
