Product Overview
The YUKEN EFG-02-30-22 is a high-performance proportional electro-hydraulic flow control valve engineered by YUKEN, a globally recognized leader in hydraulic component technology. This valve operates on a precise electro-hydraulic proportional principle, where an electrical input signal commands a proportional solenoid to modulate the spool position, thereby delivering infinitely variable flow control proportional to the command signal. Designed for demanding industrial hydraulic systems, the EFG-02-30-22 serves as a critical interface between electronic control systems and hydraulic power circuits, enabling smooth, accurate, and repeatable flow regulation for actuators, motors, and cylinders. Its robust construction and precision metering characteristics make it an ideal solution for applications requiring dynamic response and fine-tuned velocity control.
