Vickers Type KDG4V-3 Proportional Valve | KDG4V-3S-33C08A | NG6 Solenoid Valve

Vickers Type KDG4V-3 Series High-Performance Proportional Directional Valves

Product Overview: The Vickers KDG4V-3 Series is a direct-operated proportional directional spool valve featuring the universal Size 3 (NG6 / CETOP 03) mounting interface. As a benchmark of the 60-design sequence, these valves enable precise, stepless regulation of both hydraulic flow and direction based on input electrical signals. Its superior dynamic response and minimal hysteresis make it the premier choice for plastic machinery, die-casting equipment, machining centers, and precision hydraulic power units (HPUs).

This selection highlights primary configurations: the high-accuracy KDG4V-3S-33C08A-H-M-U-H5/G5-60 and the classic proportional models like the KDG4V-3-2C28S-H-M-U-G7-60.

Key Technical Advantages:

• Precision Proportional Control: Driven by high-performance proportional solenoids, these valves offer excellent linearity and repeatability, ensuring smooth and shock-free actuator movement.

• Wet-Pin Solenoid Engineering: Armatures operate fully immersed in hydraulic oil for superior self-lubrication and heat dissipation, resulting in ultra-quiet operation and an extended mechanical service life.

• Design 60 Optimization: The optimized 60-series sequence provides higher switching power limits, maintaining exceptional control sensitivity even under high-pressure and high-flow conditions.

• Versatile Electrical Interfaces: Available with H5 (DIN Standard), G5, and G7 connector options with high ingress protection, compatible with leading global electronic controllers.
