Vickers KCG Series Pilot-Operated Proportional Relief Valves

Product Overview: The Vickers KCG series is a high-performance pilot-operated proportional relief valve specifically designed for applications requiring continuous and precise hydraulic pressure regulation. By responding to a proportional electrical input signal, the KCG valve controls system pressure linearly. Whether in the compact Size 03 (NG6) or the high-flow Size 08 (NG25), KCG valves demonstrate exceptional repeatability and minimal hysteresis. The integrated Manual Override (M) provides significant convenience for system commissioning and emergency manual intervention. These valves are widely used in injection molding machines, metal forming presses, and various automated industrial hydraulic circuits.

Featured models: KCG-3-350D-Z-M-U-H1-10, KCG-8-W250-1-Z-M-U-H1-10, KCG-8-W350-3-Z-M-U-HL1-10, and KCG-3-L350D-Z-M-U-HL1-10-P15-T10.

Key Technical Advantages:

• Precise Proportional Regulation: Pressure output maintains a strict proportional relationship with the input electrical signal, supporting complex pressure profiling.

• Versatile Pressure Ranges: Available in multiple maximum pressure settings, including 250 bar (W250) and 350 bar (350D/W350), to meet various system demands.

• Superior Dynamic Stability: The pilot-operated design ensures stable system pressure even under significant flow fluctuations, effectively reducing hydraulic shock.

• High Protection & Durability: Equipped with H1/HL1 (DC24V) high-grade coils, offering excellent EMI resistance and thermal stability with industry-standard protection ratings.

• Flexible Configurations: Supports various porting options (e.g., P15/T10 specific configurations) for easy integration into manifold blocks.
