The KBXCG8W250ZM13APE7H110 is a proportional pressure reducing valve from Vickers within the Pressure Control Valves series. Intended for hydraulic automation loops, it modulates downstream pressure so actuators receive stable force under variable load conditions. The unit is built as a two-stage design in which a pilot section drives the main spool to control pressure up to 350 bar while handling flow rates to 300 L/min. It mounts on a subplate that conforms to the ISO5781-AH-08-2-A pattern, enabling direct manifold integration. The solenoid is positioned at the B-port end to simplify electrical routing, and on-board electronics negate the need for an external amplifier. A reverse-flow check valve allows free return flow when circuit direction reverses, ensuring predictable performance in regenerative circuits.
Electrical control is provided through a 7-pin connector supplied with a plug; the coil operates from a 24 V DC source and responds linearly to a ±10 V command signal issued by a motion controller or PLC. The interface choice reduces wiring complexity and supports standard analog cards. Pressure can be fine-tuned on site with a screw and locknut, yet the design offers no manual override, preventing accidental spool shifts during maintenance. Continuous service is maintained between −20 °C and 70 °C, covering mobile equipment exposed to cold starts and industrial presses that operate near ambient heat limits. Internal electronics supervise coil current and compensate for viscosity or temperature changes, maintaining calibrated pressure reduction throughout the valve’s working range.
