Yuken EDG, ERG & EFBG Series Proportional Control Valves

Product Overview: The Yuken Proportional Valve Series stands as the cornerstone for intelligent pressure and flow modulation in modern industrial hydraulic systems. This comprehensive lineup ranges from compact pilot valves like the EDG-01/ERG-01 to high-capacity compound valves in the EFBG series, supporting flow rates up to 500 L/min. Driven by high-efficiency proportional solenoids, these valves translate electrical commands into precise hydraulic power. They are essential for 2026 high-precision injection molding, metal extrusion, die-casting, and heavy-duty automated power units.

Key Technical Advantages:

• Comprehensive Pressure Range: The EDG-01 is available in H (High-pressure), C (Low-pressure), and V (with external drain) variants to suit diverse pilot requirements.

• Precision Pressure Reduction (ERG-01): The ERG-01-1113 is engineered for critical pressure-reducing circuits, ensuring minimal fluctuations in secondary-side pressure.

• Integrated Flow & Pressure Control (EFBG): Combines proportional pressure and flow regulation in a single unit for dynamic load-sensing, significantly reducing energy waste and system heat.

• Superior Repeatability: Featuring optimized magnetic circuit designs, the series maintains hysteresis within 3% and repeatability exceeding 1%.

• Rapid Dynamic Response: Advanced internal pilot channel designs ensure millisecond-level response times, matching the high-speed production cycles of 2026.
