Product Description

Vickers Type KDG4V-3 & KDG4V-5 Series Proportional Directional Valves

Product Overview: The Vickers KDG4V Series consists of direct-operated proportional solenoid valves designed for the stepless and precise regulation of flow and direction within hydraulic systems. Available in Size 3 (NG6 / CETOP 03) and Size 5 (NG10 / CETOP 05) footprints, this range offers exceptional dynamic response and control linearity. It is the premier choice for plastic machinery, die-casting equipment, heavy industrial automation, and high-precision hydraulic control circuits.

This selection highlights primary configurations: the high-flow KDG4V-5-33C50N (with Z specs) and KDG4-5-33C50N-H, alongside the compact KDG4V-3-33C30X (60-design sequence).

Key Technical Advantages:

  • Precision Proportional Control: Proportional solenoids drive the spool to precisely control actuator speeds via input current signals, effectively eliminating switching shocks.

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

  • High Dynamic Response: Optimized 30 and 60 design sequences significantly reduce hysteresis, ideal for precision applications requiring frequent and rapid switching.

  • Global Mounting Standard: Strictly adheres to ISO 4401 mounting standards, ensuring seamless integration with global proportional controllers and hydraulic manifolds.
