Product Overview
The Rexroth DBW 30 B2-52/100-6EG24N9K4 (Material Number R900922310) is a pilot-operated, solenoid-controlled pressure relief valve from the proven Rexroth DBW series. It combines the functions of a pilot-operated pressure relief valve with a directional solenoid valve, enabling both continuous system pressure limitation and electrical unloading (vent) of the hydraulic circuit. The valve is normally closed in the de-energized state; when the solenoid is energized, the pilot stage is vented to tank, allowing the main spool to open and the pump to discharge at near-zero pressure. This design makes it ideal for energy-saving pump unloading, safety overpressure protection, and controlled pressure staging in demanding industrial hydraulic power units.
