Electro-Hydraulic Proportional Relief Valves (EDG-01, ERG-01 Series)

Product Overview:

This series of Electro-Hydraulic Proportional Relief Valves is the cornerstone of automated pressure control in modern industrial hydraulic systems. The EDG-01 series serves as a pilot-operated proportional valve, enabling infinitely variable pressure adjustment based on input current. Renowned for their ultra-low hysteresis, high response frequency, and exceptional pressure repeatability, these valves are essential for precision machinery. Whether it is the EDG-01V-H for high-accuracy injection molding or the ERG-01 for pilot control in high-flow systems, they ensure superior linearity across complex operational cycles.

Featured models on this page: ERG-01-1113, EDG-01V-H-1-PNT11-5115-R, EDG-01V-H-PNT11-51, and RF-G04-1-32.

Key Technical Advantages:

• Superior Control Linearity: Utilizing optimized solenoid coils and spool geometry, ensuring stable pressure output with minimal dead zones relative to input current.

• High Dynamic Response: The EDG-01V-H is reinforced for high-frequency response, achieving millisecond-level pressure transitions—ideal for tight cycle-time requirements.

• Compact Modular/Subplate Design: Standard mounting interfaces allow for easy integration into manifold blocks, optimizing space and reducing installation complexity.

• Integrated Pilot Regulation: The RF-G04 combines proportional technology to provide smooth pressure compensation and relief protection in large-flow circuits.
