Product Overview
The Rexroth DBW10B2-5X/200-6EG24N9K4 (material number R900912910) is a pilot-operated, solenoid-controlled pressure relief valve from the proven DBW series, size 10, component series 5X. It combines a direct-acting pilot stage with a main spool stage to limit and electrically unload system pressure in hydraulic power units and manifold blocks. The valve is normally closed in its de-energized state; energizing the integrated wet-pin DC solenoid opens the pilot circuit, allowing the main spool to vent pump flow to tank at minimal pressure. The DBW10B2 configuration features an adjustable pressure setting range up to 200 bar, a 6 mm nozzle (damping orifice) for stable pilot response, and a nominal 24 V DC solenoid with N9 (DIN EN 175301-803, ISO 4400) plug connection and K4 manual override. As a pressure control valve, it performs no pumping function; it regulates, limits, and electrically dumps pressure within the hydraulic circuit.
