Product Overview
The Rexroth DBDS30K1X/315V is a direct operated pressure relief valve from the proven DBDS series, engineered by Bosch Rexroth to protect hydraulic systems against excessive pressure and to serve as a reliable pressure-limiting control element. The valve operates on a direct-acting poppet principle: system pressure acts on the valve poppet, which is held closed by an adjustable spring. When the set pressure is reached, the poppet lifts and routes excess flow to the tank port, thereby limiting system pressure to the preset value. With a nominal size of NG30 and a pressure rating of 315 bar, this valve is suited to demanding industrial circuits requiring fast response, minimal pressure override, and stable pressure regulation across the full flow range.

Engineering Features & Advantages
- Precision Pressure Limiting: Direct-acting poppet design delivers fast response and tight pressure control, minimizing pressure override and protecting downstream components from pressure spikes.
- Stable Regulation: Balanced poppet and spring assembly maintains consistent cracking and reseat behavior across the specified flow range, ensuring repeatable system protection.
- Industrial Reliability: Robust valve body and hardened internal components are built for continuous operation under severe industrial conditions and high cyclic duty.
- Adjustable Setting: The “V” adjustment variant allows precise, field-adjustable pressure setting with a lockable adjustment element to prevent tampering.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth DBDS series standards, enabling drop-in replacement without circuit modification.
Typical Industrial Applications
The Rexroth DBDS30K1X/315V is widely deployed as a system protection and pressure-limiting valve in plastic injection molding machines, metallurgical presses and rolling mills, construction and marine hydraulic systems, and CNC machine tools, where reliable overpressure protection and stable pressure control are essential to safe, continuous operation.
