Product Overview
The Rexroth DBDS 10 K 18/200 (R900424149) 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, adjustable value. As a direct acting poppet-type valve, the pressure setting is established by a mechanically adjustable spring that acts directly on the valve poppet, providing fast response and stable pressure control without pilot stage dependency. The valve opens when inlet pressure exceeds the set spring force, diverting excess flow to the tank port and thereby safeguarding downstream components such as pumps, cylinders, and directional valves. With a size 10 (NG10) mounting interface and a pressure rating of 200 bar, this model is a compact, robust solution for pressure limiting and safety functions in industrial hydraulic power units and machine circuits.

Engineering Features & Advantages
- Precision Pressure Control: Direct acting poppet design delivers fast, repeatable response to pressure surges, with minimal pressure override and stable setting behavior across the operating range.
- Adjustable Pressure Setting: The spring-loaded adjustment element allows precise, stepless setting of the relief pressure to match specific circuit protection requirements.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened, wear-resistant internal components ensuring long service life and low leakage.
- Direct Fit Replacement: Exact dimensional and functional compatibility with the original Rexroth DBDS series interface, enabling straightforward drop-in replacement without circuit modification.
- Compact Subplate Design: NG10 mounting pattern integrates easily into standard manifold and subplate assemblies, reducing installation time and system footprint.
Typical Industrial Applications
This direct operated pressure relief 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 hydraulic systems. It is equally suited to construction and marine hydraulics, where reliable overpressure protection and precise pressure setting are essential for protecting pumps,
