Yuken Proportional Valve | EDG-01-C | EFBG-03-125-C | Electro-Hydraulic Pilot Relief Valve

Yuken EDG & EFBG Series Electro-Hydraulic Proportional Valves

Product Overview:

The EDG-01 and EFBG-03 represent the standard for intelligent pressure and flow modulation in high-end hydraulic systems. The EDG-01-C is a compact proportional pilot relief valve designed to precisely govern the pilot pressure of larger valves. Complementing this, the EFBG-03-125-C is an advanced compound valve that integrates proportional pressure and flow control, allowing for dynamic output adjustment based on load demand. These valves are essential for 2026 high-precision injection molding machines, metal extruders, and sophisticated industrial power units.

Key Technical Advantages:

• Precise Proportional Pressure (EDG-01-C): Features a high-efficiency direct-acting solenoid for C (Low Pressure) regulation, ensuring minimal hysteresis and shock-free pressure transitions.

• Integrated Flow & Pressure Control (EFBG-03): With a 125 L/min flow capacity, this valve manages complex load-sensing tasks within a single unit, significantly reducing heat generation and energy waste.

• Superior Dynamic Response: Optimized internal pilot circuitry ensures millisecond-level response times, providing instantaneous feedback during rapid switching cycles.

• Industrial Durability: Cast from high-strength materials and compatible with standard DC 24V amplifiers (e.g., AME-D-10), built to withstand high-vibration and harsh manufacturing environments.

• Easy Maintenance: Standard ISO mounting interfaces (NG6/NG10) allow for effortless drop-in replacement or performance upgrades on existing machinery.
