Product Overview
The Rexroth DBW15BG2-53/200-6EG24N9K4 (Material Number R900944622) 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 pilot-operated pressure relief cartridge with a directional solenoid pilot valve, allowing it to perform two functions: continuous pressure regulation at a preset cracking level and rapid electrical venting of the main stage to unload the system on command. The DBW15 size 15 design is built around a balanced poppet main stage and a compact pilot stage, delivering stable pressure control with minimal pressure override across the full flow range. With a 200 bar pressure rating and a 24 VDC high-performance solenoid (N9K4 coil with integrated manual override), this valve is a direct-fit replacement for OEM installations and is widely deployed in plastic injection molding machines, hydraulic presses, and general industrial power units where reliable pressure control and electrical unloading are essential.
