Product Overview
The Rexroth DBW10B1-5X/315-6EG24N9K4 (Material Number R900920863) is a pilot-operated, solenoid-controlled pressure relief valve designed for precise system pressure limitation and electrical unloading in industrial hydraulic circuits. Part of the proven Rexroth DBW series (Size 10, Component Series 5X), this valve combines a pilot-operated pressure relief cartridge with a directional solenoid pilot valve, enabling both continuous pressure regulation and rapid electrical venting of the main stage. The valve is engineered for high-pressure hydraulic power units, presses, and injection molding systems where reliable overpressure protection and controlled depressurization are critical to machine safety and process repeatability.

Engineering Features & Advantages
- Precision Pressure Limiting: Pilot-operated main stage delivers accurate, stable pressure regulation with minimal pressure override across the full 315 bar range, protecting downstream components from overpressure events.
- Solenoid-Controlled Unloading: The integrated directional solenoid pilot valve allows electrical switching between pressure-holding and unloading (venting) modes, enabling rapid depressurization of accumulators and actuators without manual intervention.
- Industrial Reliability: Designed for dependable long-term operation in demanding industrial environments, with quality bearings and sealing systems ensuring extended maintenance intervals.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original REXROTH OEM standards, ensuring drop-in replacement without modification to existing manifolds or piping.
Typical Industrial Applications
The valve is engineered for high-pressure hydraulic power units, presses, and injection molding systems where reliable overpressure protection and controlled depressurization are critical to machine safety and process repeatability.
