Yuken Type ERG Series Proportional Pilot Operated Relief Valves

Product Overview: The ERG Series is a high-performance proportional pilot-operated relief valve, specifically designed to regulate hydraulic system pressure continuously and proportionally relative to input current. This series combines the high-flow handling capabilities of a pilot-operated structure with the precision of electro-proportional technology. It is widely used in injection molding machines, large hydraulic presses, industrial machine tools, and automated production lines. Whether achieving complex multi-stage pressure switching or smooth pressure ramps, the ERG series provides exceptional linearity and minimal hysteresis.

This category features the precision control model ERG-01-1113 and the high-power, high-flow ERG-06-3-R-30-10.

Key Technical Advantages:

• Precision Proportional Control: Driven by a high-performance proportional solenoid in the pilot stage, ensuring output pressure remains highly linear with input current for “intelligent” pressure regulation.

• Superior Pressure Stability: The pilot-operated design effectively dampens pressure oscillations, maintaining an extremely stable relief state even near maximum operating limits.

• Low Hysteresis & High Repeatability: Precision-ground spools and seats guarantee consistent pressure parameters across multiple cycles, improving manufacturing yields.

• Rugged & Versatile Design: Available in multiple nominal sizes, these valves easily integrate into standard manifolds and are compatible with various industrial mineral oil fluids.
