Vickers KDG4V KTG4V Valve | KTG4V-3S-2B08N-M-U-H5-60-EN427 | KTG4V-3-2B20N-Z-M-U-H7-20 | Proportional Solenoid Valve

Vickers KDG4V & KTG4V Series Direct-Operated Proportional Solenoid Valves

Product Overview:

The Vickers KDG4V and KTG4V series are high-performance, direct-operated proportional directional valves utilized extensively in industrial and mobile hydraulic applications. By employing proportional solenoids to actuate the spool directly, these valves provide stepless and precise control over both flow direction and magnitude. The KTG4V series, designed without electrical feedback, offers an exceptional balance of cost-efficiency and response linearity, making it the premier choice for injection molding machines, machine tools, and automated assembly lines. Rated for pressures up to 315 bar, this series ensures smooth operational performance in demanding environments.

Featured models: KTG4V-3S-2B08N-M-U-H5-60-EN427 and KTG4V-3-2B20N-Z-M-U-H7-20.

Key Technical Advantages:

• Direct Proportional Actuation: Solenoid force acts directly on the spool, enabling rapid response times without the need for pilot pressure.

• High Response & Linearity: Precision-ground spools paired with high-quality solenoids deliver smooth flow regulation with minimal hysteresis.

• Versatile Electrical Options: Features U-type (ISO 4400 / DIN 43650) connectors, ensuring excellent electromagnetic compatibility (EMC) and high ingress protection.

• Support for Customized Specs (EN427): Includes specialized versions like the EN427, tailored for specific flow curves or sealing requirements in unique engineering projects.

• Rugged Durability: High-strength cast bodies and thermally stable coils provide superior resistance to vibration and heat, suitable for ambient temperatures from $-20^\circ\text{C}$ to $+70^\circ\text{C}$.
