Product Overview
The Rexroth DBW30A2-5X/315-6EG24N9K4 (Material No. R900921853) is a pilot-operated, solenoid-controlled pressure relief valve from the proven DBW series, size NG30 (DN30). It combines a pilot-operated pressure relief valve with a directional spool valve in a single housing, enabling both continuous system pressure limitation and electrical unloading (vent) of the circuit via a wet-pin DC solenoid. The valve is designed for subplate mounting in accordance with ISO 6264 (size 30), and its 315 bar pressure rating makes it suitable for high-pressure industrial hydraulic power units, presses, and accumulator circuits. The “5X” designation identifies the 500-series component family, ensuring long-term availability of spare parts and interchangeability within the Rexroth modular valve program.

Engineering Features & Advantages
- Precision Pressure Limiting: Pilot-operated main stage with adjustable spring-loaded pilot valve delivers accurate, repeatable cracking pressure and low hysteresis across the full 315 bar range.
- Integrated Solenoid Unloading: The 24 V DC wet-pin solenoid acts on the pilot stage to electrically vent (unload) the system, allowing remote depressurization without additional directional valves.
- 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 designed for subplate mounting in accordance with ISO 6264 (size 30), and its 315 bar pressure rating makes it suitable for high-pressure industrial hydraulic power units, presses, and accumulator circuits.
