Product Overview
The Rexroth DBW10B2-5X/350S6EG24N9K4R12 (material number R900970306) is a pilot-operated, solenoid-controlled pressure relief valve from the proven DBW series, size 10 (NG10 / CETOP 5). It combines a pilot-operated pressure relief cartridge with a directional solenoid valve that enables electrical unloading (venting) of the pilot stage. In industrial hydraulic systems, this valve limits system pressure to a preset value, protects downstream components against overpressure, and allows remote or electrical switching between pressure-holding and depressurized circulation modes. The “5X” designation identifies the 500-series component family, ensuring long-term availability and dimensional interchangeability with the original Rexroth design.

Engineering Features & Advantages
- Precision Performance: Pilot-operated main stage delivers accurate, repeatable pressure limitation with minimal pressure override and stable response across the full 350 bar adjustment range.
- Solenoid Unloading Function: The integrated directional solenoid valve vents the pilot stage on command, allowing the main stage to open fully and depressurize the system for energy-saving circulation or safe maintenance sequences.
- Industrial Reliability: Constructed for continuous duty with durable, corrosion-resistant materials and proven engineering for maximum system uptime.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original REXROTH standards, allowing straightforward retrofit into existing hydraulic systems without rework.
Typical Industrial Applications
In industrial hydraulic systems, this valve limits system pressure to a preset value, protects downstream components against overpressure, and allows remote or electrical switching between pressure-holding and depressurized circulation modes.
