Vickers Type KBFTG4V-3 Valve | KBFTG4V-3-2B13N | Integrated OBE Proportional Valve

Vickers Type KBFTG4V-3 Series Proportional Valves with Integrated OBE

Product Overview: The Vickers KBFTG4V-3 Series is a direct-operated, high-response proportional directional valve engineered for hydraulic circuits requiring extreme precision and dynamic control. The defining feature of this series is the Integrated On-Board Electronics (OBE), where spool position is monitored via a closed-loop LVDT (Inductive Transducer). This allows the valve to compensate for flow errors caused by pressure fluctuations in real-time, providing laboratory-grade fluid control for injection molding, die-casting, and simulation testing equipment.

The featured model KBFTG4V-3-2B13N-Z-M1-PE7-H7-12 represents the peak performance of this series in the compact Size 3 (NG6) configuration.

Key Technical Advantages:

• Integrated OBE (On-Board Electronics): The built-in electronic control unit is factory-calibrated for gain and zero-point, significantly simplifying external wiring while eliminating EMI effects on analog signals.

• High Frequency Response & Low Hysteresis: Powered by robust solenoids and LVDT feedback, these valves exhibit servo-like frequency response with minimal hysteresis, ensuring smooth and rapid actuator movements.

• Closed-Loop Position Control: The internal transducer provides real-time spool feedback, maintaining exceptional flow linearity and repeatability even under high-pressure conditions.

• Industrial Durability: Utilizing high-standard connectors (PE7) and IP65/67 rated protection, the valve is built to withstand harsh industrial environments including high temperatures, humidity, and vibration.
