Product Overview
The YUKEN EFBG-03-125-H-21T233-L is a high-performance proportional electro-hydraulic flow control and relief valve from YUKEN’s renowned EFBG series. This dual-function component integrates precise proportional flow control with an integral pilot-operated relief valve, allowing simultaneous regulation of actuator speed and system pressure within a single compact body. The valve operates on a proven proportional solenoid principle: an electrical command signal drives the proportional solenoid, which positions the metering spool against a spring force to deliver infinitely variable flow output proportional to the input current. The integrated relief function provides system overpressure protection and permits pressure-compensated flow control, ensuring stable actuator motion regardless of load fluctuations. With a nominal size of 03 (NG10 / CETOP 5 interface), the EFBG-03-125-H-21T233-L is engineered for demanding industrial hydraulic circuits requiring precise velocity and pressure management, making it an ideal choice for injection molding machines, hydraulic presses, and advanced motion control systems.
