Product Overview
The Rexroth DBW 20 A2-52/350-6EG24N9K4 is a pilot-operated, solenoid-controlled pressure relief valve designed for precise system pressure limitation and electrical unloading in industrial hydraulic circuits. Part of the renowned Rexroth DBW series, this valve combines a pilot stage with a main spool stage to deliver stable pressure control even at high flow rates. The integrated directional solenoid allows the valve to be electrically switched between pressure-relief and unloading functions, making it ideal for energy-efficient systems requiring remote or automated pressure management. With a nominal size of NG20 and a pressure rating of 350 bar, it is engineered for demanding continuous-duty applications in heavy machinery and industrial power units.
