Product Overview
The Rexroth DBDS6P1C/270E (Material No. R901169152) is a direct operated pressure relief valve from the proven DBDS series, engineered to protect hydraulic systems against excessive pressure and to limit system pressure to a preset value. As a direct acting poppet-type valve, the pressure setting is infinitely adjustable via a mechanical adjustment element, and the valve responds almost instantaneously to pressure peaks without pilot-stage lag. With a nominal size of NG6 and a pressure rating of 270 bar, this valve is designed for compact manifold mounting in industrial power units, machine tools, and test rigs where fast, reliable overpressure protection is essential.

Engineering Features & Advantages
- Precision Performance: Direct operated poppet design delivers fast response to pressure peaks and tight pressure regulation with minimal hysteresis and low internal leakage.
- Industrial Reliability: Robust valve body and hardened internal components are built for continuous operation under severe industrial conditions and high cyclic duty.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, including the ISO 4401-03 mounting interface and R901169152 part number traceability.
- Simple, Stable Setting: Mechanical pressure adjustment with locknut allows precise, repeatable setting of the relief pressure without auxiliary pilot supply.
Typical Industrial Applications
This valve is widely deployed as a safety and pressure-limiting element in hydraulic power units, plastic injection molding machines, metallurgical presses, CNC machine tools, and general industrial test stands. It is equally suited to mobile and marine hydraulic circuits where compact NG6 manifold mounting and dependable 270 bar overpressure protection are required.
