Product Overview
The Rexroth DBW 30 B2-52/100U6EG24N9K4 (Material No. R900941761) is a pilot-operated, solenoid-controlled pressure relief valve designed for precise system pressure limitation and electrical unloading in industrial hydraulic power units. Part of the proven Rexroth DBW series, this valve combines a main pressure relief stage with a solenoid-actuated pilot valve, allowing remote electrical selection between pressure-loaded and unloaded system states. The valve is normally closed in the de-energized condition, building pressure to the set value; energizing the solenoid vents the pilot stage to unload the system. With a nominal size of NG30 (DIN 24340), the DBW 30 B2-52/100U6EG24N9K4 is engineered for high-flow circuits requiring reliable, repeatable pressure control and fast electrical switching.
