Product Overview
The Rexroth DBW 10 B2-53/200-6EG24N9K4 (Material Number: R900912910) is a pilot-operated, solenoid-controlled pressure relief valve from the proven DBW series, engineered for precise system pressure limitation and electrical unloading in industrial hydraulic circuits. This valve combines a direct-acting pilot stage with a main spool stage, allowing it to handle high flow rates while maintaining accurate pressure control. The integrated normally closed (N9) solenoid enables remote electrical actuation for depressurizing the system or switching between pressure levels. With a nominal size of NG10 (Size 10) and a pressure rating of 200 bar, this valve is a direct-fit replacement for OEM installations and is widely used in demanding hydraulic power units, presses, and injection molding machinery.
