Product Overview
The Rexroth DBDS 20 G 1X/315 (Material No. R900424174) is a direct operated pressure relief valve from the proven DBDS series, engineered by Bosch Rexroth for precise system pressure limitation and protection in industrial hydraulic circuits. As a direct acting poppet-type pressure control valve, it responds instantaneously to pressure surges without pilot-stage lag, making it ideal for applications requiring fast, reliable overpressure protection. The valve is set to a nominal cracking pressure of 315 bar and is designed for inline mounting in hydraulic power units, manifolds, and compact control blocks. Its robust housing and hardened internal components ensure stable pressure regulation, minimal internal leakage, and long service life even under continuous duty in demanding industrial environments.

Engineering Features & Advantages
- Precision Performance: Direct operated poppet design delivers fast response to pressure peaks with minimal pressure override, ensuring accurate and repeatable system pressure limitation.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened valve seat and damping elements that resist wear, contamination, and pressure pulsation.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, allowing drop-in replacement without modification to existing manifolds or piping.
- Adjustable Pressure Setting: Set screw with locknut enables fine adjustment of cracking pressure across the valve’s rated range for application-specific tuning.
- Low Internal Leakage: Precision-matched poppet and seat geometry minimizes leakage losses, improving overall hydraulic system efficiency and thermal stability.
Typical Industrial Applications
The Rexroth DBDS 20 G 1X/315 is widely deployed as a safety and pressure-limiting valve in plastic injection molding machines, metallurgical presses and rolling mills, construction and marine hydraulic systems, CNC machine tools, and general industrial power units where reliable overpressure protection up to 315 bar is required. Its direct acting response makes it particularly suited to circuits subject to rapid pressure spikes or where a compact, manifold-mounted relief function is preferred over pilot-operated alternatives.
