Product Description
Vickers Type KFDG4V & KDG4V Series Proportional Directional Valves
Product Overview: The Vickers KFDG4V and KDG4V Series are direct-operated solenoid valves engineered for precise proportional control of hydraulic fluid flow and direction. Utilizing the standard Size 3 (NG6 / CETOP 03) mounting interface, these valves provide accurate regulation of actuator speed and position based on input signals.
The KFDG4V Series features an integrated LVDT displacement transducer (Position Feedback) for real-time spool monitoring and closed-loop control. This significantly eliminates hysteresis and enhances dynamic response. The KDG4V Series offers a cost-effective solution for open-loop proportional requirements. They are widely used in injection molding, machine tools, synchronized control systems, and high-performance industrial HPUs.
Key Technical Advantages:
Precision Feedback Technology (KFDG Series): The internal LVDT sensor ensures spool position matches commands exactly, providing superior linearity and repeatability.
High Dynamic Response: Optimized proportional solenoids deliver rapid response times, ideal for high-frequency switching applications.
Wet-Pin Solenoid Engineering: The armature operates immersed in oil for self-lubrication and shock absorption, ensuring quiet operation and extended mechanical service life.
FKM Sealing (VM/V): Equipped with high-quality seals for temperature resistance and compatibility with various synthetic and mineral hydraulic fluids.
