Vickers Type KDG4V Series Proportional Directional Control Valves

Product Overview: The KDG4V Series consists of solenoid-operated proportional directional valves engineered for hydraulic systems requiring precise control of actuator speed, position, or direction. Designed as a non-feedback (open-loop) proportional solution, this series features superior fluid dynamics and high-resolution solenoid actuation for excellent linearity and repeatability.

This category covers two essential frame sizes: Size 03 (NG6) for model KDG4V-3 and the high-capacity Size 05 (NG10) for KDG4V-5. Whether equipped with 2C28S or 2C50N spool configurations, the series provides smooth acceleration and deceleration control under high-pressure conditions. It is the premier choice for injection molding machinery, metal forming equipment, hoisting controls, and industrial automation lines.

Key Technical Advantages:

• Precision Proportional Control: Spool displacement is directly proportional to input current, enabling stepless regulation of hydraulic flow and ensuring shock-free operation.

• High Dynamic Response: Optimized wet-pin solenoids deliver millisecond-level response times, meeting the requirements of complex dynamic duty cycles.

• Versatile Flow Capacities: Offers various spool sizes from 28 L/min (Size 03) up to 50 L/min (Size 05) to perfectly match load requirements.

• Industrial Reliability: Equipped with high-grade seals for superior contamination resistance and extended service life, built for 24/7 continuous industrial operation.
