Yuken Type EBG & EDG Series Proportional Electro-Hydraulic Relief Valves

Product Overview: The EBG and EDG Series are premium proportional valve components designed for precision remote pressure regulation in hydraulic systems. By utilizing a proportional solenoid to directly actuate the pilot spool, these valves linearly convert command current into hydraulic pressure output. The EDG Series typically functions as a pilot control valve, while the EBG Series integrates the proportional pilot with a main relief stage to form a high-flow proportional control unit. Designed under the 51 Design Sequence, they offer exceptional stability and response.

This category covers the complete range of specifications: including the subplate-mounted EBG-03, EBG-06, and EBG-10, alongside high-performance configurations like the EBG-03-H-R (with safety relief/remote control). Available in B (Low), C (Medium), and H (High) pressure adjustment ranges, these valves are the premier choice for injection molding machines, die-casting equipment, automated test benches, and metallurgical machinery.

Key Technical Advantages:

• Precision Proportional Regulation: High-performance solenoids ensure an outstanding linear relationship between output pressure and input current with minimal hysteresis.

• Multiple Pressure Tiers: Available in B (0.7-7 MPa), C (1-16 MPa), and H (1.2-25 MPa) spring ratings to match various system pressure limits.

• Rapid Dynamic Response: Optimized internal throttling ensures fast response times during pressure transitions and ramping without significant oscillations.

• High Versatility: Supports external drain (T) configurations, with models like F9 or R offering flexible remote pressure setting capabilities.
