Yuken EFBG Series Valve | EFBG-03-125, EFBG-06-250, EFBG-10-500 | Proportional Flow & Pressure Control

EFBG Series Proportional Electro-Hydraulic Relief & Flow Control Valves

Product Overview: The Yuken-style EFBG series is a highly integrated proportional valve designed for simultaneous and independent regulation of Pressure and Flow within hydraulic systems. Classified as an energy-saving Load Sensing Valve, the EFBG series integrates proportional relief and flow control functions. It ensures the pump’s output pressure remains just slightly above the load requirements, significantly minimizing power loss, reducing oil temperature, and extending the service life of hydraulic components.

Featured Models: EFBG-03-125, EFBG-06-250, and EFBG-10-500.

Key Technical Advantages:

• Dual Functionality: Accomplish both pressure and flow proportional control in a single valve body, simplifying manifold design and reducing potential leak points.

• Energy Efficiency: Leveraging Load Sensing technology, the valve consumes only the minimum power required by the load, improving efficiency by over 30% compared to standard systems.

• High Dynamics & Low Hysteresis: Optimized pilot-stage architecture ensures smooth transitions and high repeatability, with hysteresis kept under 3%.

• Versatile Flow Range: Available in capacities from 125 L/min to 500 L/min, suitable for diverse applications from injection molding to heavy-duty industrial presses.

• High-Pressure Reliability: Rated for operating pressures up to 24.5 MPa (245 bar), maintaining stability in the harshest industrial environments.
