Product Overview
The Rexroth DR 10 DP2-44/75YM (Material Number R900500547) is a direct-operated, pilot-assisted pressure reducing valve from the proven Rexroth DR series, engineered to maintain a constant reduced outlet pressure regardless of fluctuations in the primary (inlet) pressure or changes in flow demand. As a normally open, spring-loaded pressure control valve, it reduces a higher system pressure to a stable, adjustable secondary pressure suitable for downstream branches of an industrial hydraulic circuit. The valve is a sandwich-style, manifold-mounted component with a size 10 (NG10 / CETOP 5) interface, making it a direct-fit replacement for OEM Rexroth installations and compatible with standard ISO 4401 mounting patterns. Its robust spool-and-sleeve design delivers precise pressure regulation, low hysteresis, and reliable performance in continuous-duty hydraulic power units, presses, and machine tool systems.

Engineering Features & Advantages
- Precision Performance: The direct-operated spool design maintains a constant reduced outlet pressure with minimal hysteresis and fast response, even under varying flow and inlet pressure conditions.
- Stable Pressure Regulation: Spring-loaded adjustment provides smooth, repeatable setting of the secondary pressure, protecting downstream actuators, valves, and instrumentation from over-pressure events.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened spool and sleeve for long service life and contamination tolerance.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, including the NG10 / CETOP 5 mounting interface and R900500547 material number.
- Compact Sandwich Design: Manifold-mounted configuration minimizes piping, reduces leakage points, and simplifies integration into existing hydraulic power units.
