Product Overview
The YUKEN EDG-01-C-PNTN-5101 is a proportional electro-hydraulic pilot relief valve engineered for precise, infinitely variable pressure control in industrial hydraulic systems. Manufactured by YUKEN, a globally recognized leader in fluid power technology, this valve combines a high-performance proportional solenoid with a balanced pilot relief stage to deliver smooth, stepless pressure regulation proportional to the input electrical command signal. Unlike fixed-setting relief valves, the EDG-01 series enables dynamic pressure modulation through analog or PWM amplifier control, making it ideal for systems requiring programmable pressure profiles, soft-start/stop ramps, and closed-loop pressure feedback. The “C” designation indicates a specific pressure range and coil configuration, while the “PNTN-5101” suffix defines the electrical connector type, solenoid rating, and factory-set adjustment parameters. This valve serves as a critical control element in injection molding machines, hydraulic presses, and test stands where accurate, repeatable pressure control directly impacts product quality and process efficiency.
