ERG-01-1113 Yuken Proportional Electro-Hydraulic Relief Valve

Product Overview

The ERG-01-1113 is a YUKEN ERG Series hydraulic control valve. Public YUKEN product catalog records identify the model as an ERG Valve, while YUKEN engineering documentation confirms the use of an ERG-01-11 pilot valve within related hydraulic valve assemblies.

The ERG series should therefore be positioned as an electro-hydraulic proportional pressure-control solution, rather than being described simply as a conventional on/off solenoid valve.

For replacement applications, the complete model number ERG-01-1113 should be verified together with mounting dimensions, port configuration, solenoid specification, pilot circuit and pressure-control characteristics.

Our replacement solution focuses on direct interchangeability and 100% simulated working-condition testing, helping reduce commissioning risk when replacing an original YUKEN hydraulic valve.

Key Technical Advantages

1. Electro-hydraulic proportional pressure control

The ERG product family is intended for hydraulic pressure-control applications where electrical commands need to influence hydraulic pressure, making it suitable for automated industrial hydraulic systems.

2. Pilot-controlled architecture

YUKEN engineering documentation identifies ERG-01-11 as a pilot valve. A pilot stage allows a comparatively small control element to influence the main hydraulic circuit, providing a practical architecture for pressure-control applications.

3. Automation compatibility

Electro-hydraulic proportional pressure control can be integrated into PLC-based systems, pressure feedback loops and automated hydraulic power units where pressure setpoints must change according to machine operating conditions.

4. Replacement-oriented engineering

The complete ERG-01-1113 identification is important for replacement applications. Matching the full model helps reduce the risk of incorrect installation caused by differences in electrical configuration, mounting, pressure range or pilot circuit.

5. Industrial hydraulic application

Public trade data confirms ERG-01-1113 being used in hydraulic transmission applications, supporting its relevance to industrial hydraulic equipment.

Application Areas

Typical target applications include:

• Industrial hydraulic power units
• Hydraulic pressure-control systems
• Hydraulic presses
• Injection molding hydraulic circuits
• Metal forming machinery
• Automated hydraulic machinery
• Industrial pressure regulation systems
• Hydraulic test equipment
• YUKEN hydraulic valve replacement projects

Final application compatibility should always be verified against the machine hydraulic schematic and the complete original valve ordering code.

Expert Maintenance Tips

Verify the complete ordering code

Do not select a replacement using only ERG-01 or ERG-03. Verify the complete model:

ERG-01-1113

and compare it against the machine nameplate and original hydraulic documentation.

Inspect the pilot circuit

Because YUKEN documentation confirms the use of the ERG-01-11 pilot valve, contamination, insufficient pilot pressure or abnormal pilot-drain conditions should be considered during troubleshooting and maintenance.

Confirm the solenoid specification

Some third-party records identify ERG-01-1113 as a 24 VDC configuration, but this has not been independently confirmed from the currently accessible YUKEN official datasheet. Verify the original nameplate and ordering documentation before applying power.

Commission progressively

After installation, verify electrical operation, pilot connections, hydraulic port configuration and leakage before progressively increasing system pressure.

Maintain hydraulic cleanliness

Clean hydraulic oil and proper filtration are important for proportional/pilot-controlled hydraulic valves because contamination can affect small internal control passages and negatively influence pressure stability.
