EDG & EBG Series High-Response Proportional Electro-Hydraulic Relief Valves

Product Overview:

The EDG-01 and EBG series are critical components for achieving precision pressure control in hydraulic systems. As proportional pilot relief valves, they convert electrical current inputs into linear hydraulic pressure outputs. This “Electro-to-Pressure” conversion simplifies complex pressure stepping, smooth ramping, and remote pressure adjustment. While the EDG-01 is primarily used as a pilot stage, the EBG series is designed for main circuit regulation in high-flow applications. Their robust engineering ensures ultra-low hysteresis and exceptional repeatability under high-frequency industrial duty cycles.

Featured models include: EDG-01-H, EDG-01-B-PNT22-5016, and EDG-01-C-PNT13-51.

Key Technical Advantages:

• Linear Pressure Regulation: Pressure scales linearly with current input, enabling digital pressure curve control via PLC or dedicated proportional amplifiers.

• Multiple Pressure Ranges: Available in B (Low), C (Medium), and H (High) ranges to suit diverse requirements from auxiliary circuits to high-load systems.

• PNT Specialized Configuration: The PNT22 and PNT13 interfaces are optimized for specific industrial applications, ensuring OEM compatibility for injection molding and brick-pressing machinery.

• Wet-Pin Proportional Solenoids: The oil-filled coil ensures superior heat dissipation and dampens mechanical shock, significantly extending operational life.
