Product Overview The Yuken EBG Valve serves as the “pressure regulator” in modern automated hydraulic systems. Unlike standard relief valves that are manually set to a fixed pressure, the EBG allows the machine controller (PLC) to vary the pressure dynamically during a cycle—for example, offering low pressure during idling and high pressure during clamping.
Is it a “Servo Valve”? While often searched as a “servo valve” due to its electronic control and high precision, the EBG is technically a Proportional Valve.
-
Proportional (EBG): Controls pressure based on current. Used for force control.
-
Servo Valve (e.g., Yuken ES series): Typically controls flow/direction with extremely high frequency response. Used for position control.
-
Note: The EBG is often used alongside servo valves in high-end systems to manage the main system pressure efficiently.
Why Choose Yuken EBG?
-
Low Noise: The specially designed main valve spool minimizes chatter and fluid noise, improving the factory environment.
-
High Stability: Provides consistent pressure regulation even with fluctuating flow rates.
-
Fast Response: Good dynamic response to step changes in command signals.
-
Safety Options: Available with an integral manual safety valve (relief valve) to protect the system against pressure spikes if the electrical signal fails.
Compatible Power Amplifiers: To drive the EBG valve, a specific PWM power amplifier is required:
-
AME-D-10-*-20 (DC Input, Compact Type)
-
AME-D2-1010-11 (DC Input, Digital Type)
-
SK1022-–-11 (Euro Card Type)
