Yuken EFBG Series Proportional Pressure & Flow (P-Q) Control Valves

Product Overview:

The Yuken EFBG series is a high-performance, integrated solution for energy-saving hydraulic control. As a composite proportional valve, it simultaneously regulates both system pressure and flow based on electrical command signals, ensuring the power output perfectly matches the load demand. From the mid-range EFBG-03 (125 L/min) to the high-capacity EFBG-06 (250 L/min), these valves are essential in 2026 for high-speed injection molding machines, aluminum extruders, and brick presses, significantly reducing power loss and enhancing control precision.

Featured models: EFBG-03-125/160/60-C-20T233-L, EFBG-06-250-C/H, and EFBG-06-250-H-20T145.

Key Technical Advantages:

• Dual P-Q Proportional Control: Manages both pressure and flow within a single valve body, simplifying circuit design and minimizing installation footprint.

• Versatile Flow Capacities: Available in 60, 125, 160, and 250 L/min sizes to suit everything from precision adjustments to heavy-duty power requirements.

• Tiered Pressure Ratings (C/H):

  • C-Grade: Optimized for low-pressure precision (up to 14 MPa).

  • H-Grade: Engineered for high-pressure systems (up to 24.5 MPa).

• Special Design Sequences: Supports specific industrial sequences such as 20T233 and 20T145, optimized for reduced hysteresis and specific control logic.

• Proven Energy Efficiency: By matching pressure and flow to actual demand, the EFBG series drastically cuts overflow energy loss and limits oil temperature rise.
