EPCG2 Series Pilot-Operated Proportional Relief Valves

Product Overview:

The EPCG2 series represents high-performance, pilot-operated proportional relief valves designed for hydraulic systems requiring remote, continuous, and high-precision pressure regulation. By utilizing a proportional solenoid to modulate the pilot pressure, this valve achieves a linear relationship between system pressure and input current. From the compact EPCG2-01 (NG6) to the high-flow EPCG2-10 (NG32), the series is renowned for its low hysteresis, exceptional repeatability, and stability, making it ideal for injection molding, die-casting, and industrial power units.

Featured models: EPCG2-01-210-11, EPCG2-01-175-11, and EPCG2-10-35-Y-L-10-S1.

Key Technical Advantages:

• Precise Proportional Pressure Control: Features high-linearity solenoids for smooth, stepless adjustment from minimum pressure to rated levels (up to 210 bar).

• High Dynamic Response: The optimized pilot-operated structure ensures rapid, shock-free pressure transitions even under complex load changes.

• Versatile Specifications: Available in various pressure ranges (35/175/210 bar) and flow capacities to perfectly match requirements from precision machine tools to heavy-duty hydraulic systems.

• Superior Linearity & Repeatability: Hysteresis is maintained within 3%, ensuring consistent operation in high-frequency 2026 automated production environments.
