EFBG Series Proportional Pressure & Flow Control Valves

Product Overview: The EFBG series is a high-performance proportional electro-hydraulic control valve that integrates both pressure and flow control functions. By receiving proportional electrical current signals, it independently and continuously regulates system pressure and flow rates. Its unique slide valve architecture makes it exceptionally effective for braking, sliding, and multi-stage speed switching in injection molding and die-casting machines. The EFBG series is the definitive choice for precision hydraulic systems, offering low hysteresis, high repeatability, and significant energy-saving benefits.

Featured models include: EFBG-03-250-H-5114, EFBG-10-500-C, and EFBG-06-250-H-20T145.

Key Technical Advantages:

• Composite Pressure/Flow Control: Consolidates speed and force regulation into a single unit, simplifying hydraulic circuit design and reducing manifold space.

• Superior Dynamic Response: Optimized solenoid-to-spool interaction ensures millisecond-level transitions between low and high states of pressure and flow.

• Energy Efficiency: Reduces redundant overflow losses, resulting in lower system temperatures and extended seal and fluid longevity.

• Broad Capacity Range: Available from Size 03 to Size 10, supporting high-capacity flow control up to 500 L/min.
