Vickers KBFDG5V Series High-Performance Proportional Valves

Product Overview:

The Vickers KBFDG5V series is a range of two-stage, pilot-operated proportional directional valves engineered for high-dynamic applications. These valves feature Integrated On-Board Electronics (OBE), eliminating the need for external amplifiers and simplifying system integration. By utilizing electrical feedback for the main spool position, the KBFDG5V series provides servo-level repeatability and dynamic response. Whether using the KBFDG5V-5 (NG10) or the KBFDG5V-7 (NG16), its superior performance makes it the preferred solution for injection molding, blow molding, and complex industrial closed-loop circuits.

Featured models: KBFDG5V-7-33C160N, KBFDG5V-7-2C200N-X-M1-PE7-H1-10, and KBFDG5V-5-2C95N-X-M1-PE7-H1-10.

Key Technical Advantages:

• Integrated OBE Technology: Factory-calibrated control electronics are mounted directly on the valve, reducing wiring complexity and enhancing electromagnetic compatibility (EMC).

• High-Dynamics Two-Stage Design: The pilot-operated stage ensures precise spool movement, maintaining exceptional frequency response even under high flow and high-pressure conditions.

• Closed-Loop Feedback: Real-time monitoring of spool displacement reduces hysteresis to below $0.5\%$, guaranteeing consistent operational accuracy.

• Standard Mounting Interfaces: Complies with ISO 4401 standards for Size 5 (NG10) and Size 7 (NG16), allowing for easy drop-in replacement or system upgrades.

• Environmental Durability: Robust housing and advanced sealing (PE7/H1 specs) ensure reliability with mineral oils in the harshest industrial environments.
