Product Overview
The Rexroth DBW10B2-52/50-6EG24N9K4 (Material No. R900921748) is a pilot-operated, solenoid-controlled pressure relief valve from the proven DBW series, designed for precise system pressure limitation and electrical unloading in industrial hydraulic circuits. The valve combines a pilot-operated pressure relief cartridge with a directional solenoid pilot valve, allowing it to perform two functions: continuous pressure regulation at the set spring value and rapid electrical depressurization of the system via the integrated solenoid. The DBW10B2-52/50-6EG24N9K4 is a size 10 (NG10) valve with a 50 bar pressure adjustment range, a 24 V DC solenoid, and a design series 52 configuration. It is engineered for panel or manifold mounting in high-cycle industrial power units where reliable pressure control and safe electrical unloading are essential.
