Product Overview
The Rexroth DBW10B1-52/315-6EG24N9K4 (Material No. R900920863) 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 circuits. The valve combines a pilot-operated pressure relief cartridge with a directional solenoid pilot valve, allowing it to perform two functions: continuous pressure regulation across the full flow range and rapid, electrically commanded depressurization of the system. The “315” designation indicates a maximum pressure setting of 315 bar, while the “EG24” solenoid operates on 24 V DC. With a size 10 (NG10) mounting interface, this valve is a direct-fit component for standardized manifold and subplate installations in high-pressure hydraulic power units, presses, and injection molding machinery.

Engineering Features & Advantages
- Precision Pressure Control: Pilot-operated spool and poppet design delivers accurate, repeatable pressure limitation with minimal hysteresis across the full flow range.
- Electrical Unloading Function: The integrated 24 V DC solenoid pilot valve enables remote, electrically commanded depressurization of the circuit, ideal for automated cycle control and safety interlocks.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened internal components and a robust cast housing rated to 315 bar.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in replacement without manifold modification.
Typical Industrial Applications
This valve is widely deployed in plastic injection molding machines, metallurgical presses, CNC machine tools, and general industrial hydraulic power units where reliable pressure limitation and electrical unloading are required. It is also found in construction and marine hydraulic systems demanding high-pressure, solenoid-controlled pressure regulation.
