Product Overview
The Rexroth DBW10B1-LX1/315-6EG24N9K4 (material number L630700010) 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 power units. The valve combines a manually adjustable pilot stage with a normally closed directional solenoid (type “6E”, 24 V DC), allowing the main stage to be switched between pressure-holding and depressurized (unloading) states via an electrical signal. With a nominal size of NG10 (size 10) and a pressure rating of 315 bar, this valve is engineered for high-pressure circuits requiring reliable, repeatable pressure control and fast electrical venting of pump flow.
