Product Description
Vickers KBFDG4V & KBFDG5V Proportional Valves with Integrated Electronics (OBE)
Product Overview: The Vickers KBFDG series represents the pinnacle of high-performance closed-loop control in industrial hydraulic systems. These valves feature Integrated On-Board Electronics (OBE), eliminating the need for external amplifier cards by processing analog command signals directly on the valve. From the direct-operated KBFDG4V to the pilot-operated KBFDG5V, this range offers rapid frequency response, minimal hysteresis, and exceptional linearity, making it ideal for injection molding, die-casting, and sophisticated automation lines.
Featured models include: KBFDG4V-5-2C50N-Z-M1-PE7-H7-11 and KBFDG5V-8-33C375N250-X-M2-PE7-H1-11.
Key Technical Advantages:
Integrated On-Board Electronics (OBE): The factory-calibrated electronics simplify wiring, enhance noise immunity, and provide a “plug-and-play” experience for precision control.
LVDT Spool Feedback: Real-time spool position sensing ensures highly consistent performance regardless of changes in system pressure or fluid viscosity.
High Flow Capacity: The Size 8 (NG25) variant manages flow rates exceeding 600 L/min, providing precise handling for heavy-duty machinery.
Industrial-Grade Protection: Designed with PE7 specifications to withstand industrial oil mists, mechanical vibrations, and electromagnetic interference.
