Product Overview
The Rexroth DBW10B2-52/315-6EG24N9K4 (Material Number R900919570) 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 value and rapid, electrically commanded depressurization of the system. The main stage is controlled by the pilot pressure differential, while the integrated solenoid pilot valve (24 V DC) directs pilot flow to load or unload the main poppet. With a nominal size of NG10 (Size 10) and a maximum pressure rating of 315 bar, this valve is engineered for high-pressure hydraulic power units, presses, and injection molding machines where reliable pressure control and fast unloading cycles are essential.
