ESHG-06-2-320-ET-1012 Yuken Proportional Valve

Product Overview

The ESHG-06-2-320-ET-1012, EDG, ESHG, EHDG, EHBG, EHFG, EHFCG, EHFBG and EHDFG belong to the Yuken E-series proportional electro-hydraulic control valves. This series includes proportional pilot relief valves, proportional flow control valves and high-response proportional directional/flow valves that precisely control pressure or flow via electrical signals. Fully interchangeable with original Yuken units, every valve undergoes 100% simulated operating-condition testing for accurate proportional control in hydraulic systems.

Technical Specifications 

• Model: ESHG-06-2-320-ET-1012 / EDG / EHDG etc. (Yuken E-series proportional valves)
• Type: Proportional solenoid control valve (pilot relief, flow or directional)
• Maximum operating pressure: typically 24.5–35 MPa (model-dependent)
• Maximum flow: up to several hundred L/min depending on size (ESHG-06 higher flow capability)
• Pressure/flow adjustment range: model-specific (e.g. EDG 0.5–24.5 MPa)
• Hysteresis: typically < 3–5%
• Repeatability: < 1%
• Solenoid: DC proportional solenoid
• Mounting: Sub-plate or threaded
• Hydraulic fluid: Petroleum-based

Key Technical Advantages

1. Precise proportional control: Electrical signal is proportional to pressure or flow for stepless accurate regulation.
2. Low hysteresis and high response: Low hysteresis and excellent repeatability suit closed- or open-loop precision control.
3. High interchangeability: Identical interfaces and performance to original Yuken E-series enable direct drop-in replacement.
4. 100% functional verification under simulated conditions: Every unit is fully tested across electrical signal-to-pressure/flow characteristics before shipment.

Application Areas

• Proportional pressure/flow control on injection molding and die-casting machines
• Speed and force control on machine tools and precision equipment
• Precise actuator regulation on construction machinery
• Proportional circuits in industrial hydraulic power units
• Automated systems requiring electro-hydraulic proportional control

Expert Maintenance Tips

Ensure clean interfaces and tighten to the specified torque. Maintain required fluid cleanliness. Match solenoid current and signal correctly. Periodically check null and proportional characteristics. If hysteresis increases or regulation becomes unstable, first inspect fluid contamination. For long-term storage keep the valve filled with oil. Always use original-specification seals when servicing.
