Product Overview
The YUKEN EHDG-01V-H-PNT11-50 is a high-performance proportional electro-hydraulic pilot relief valve engineered for precise pressure control in demanding industrial hydraulic systems. Manufactured by YUKEN, a global leader in fluid power technology, this valve combines a proportional solenoid pilot stage with a balanced poppet main relief stage to deliver infinitely variable pressure regulation proportional to the input electrical signal. Unlike fixed-pressure relief valves, the EHDG-01V series enables continuous, stepless adjustment of system pressure through an electronic amplifier, making it ideal for applications requiring dynamic pressure profiling, soft-start/stop sequences, and closed-loop pressure control. The “01” size designation indicates a nominal 1/4″ (NG6) mounting interface, while the “50” design number denotes the specific YUKEN design series. This valve is a direct-fit, drop-in replacement for OEM YUKEN proportional controls and is widely deployed in injection molding, die-casting, and metallurgical press systems where precise pressure modulation is critical.
