Product Overview
The Rexroth DR 10 DP2-44/75YM (Material No. R900528547) is a direct-operated, pilot-assisted pressure reducing valve from the proven Rexroth DR series, designed to maintain a constant reduced outlet pressure regardless of fluctuations in the inlet (primary) pressure or changes in flow demand. As a member of the DR 10 family, this valve features a 10 mm nominal size (NG10 / CETOP 5 interface) and a spool-type pressure reducing cartridge that regulates secondary circuit pressure with high accuracy and repeatability. The DP2-44/75YM configuration is factory set to a reduced pressure of 75 bar and includes a pressure gauge connection port for on-site monitoring and adjustment verification. The valve is engineered for panel or manifold mounting in industrial hydraulic power units, where it protects downstream actuators, clamping circuits, and pilot stages from overpressure while delivering stable, metered pressure to sensitive sub-circuits.

Engineering Features & Advantages
- Precision Performance: Direct-operated spool design maintains a constant reduced outlet pressure with minimal hysteresis and excellent pressure override characteristics, ensuring stable downstream circuit behavior even under varying flow demand.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened, precision-ground spool and sleeve components that resist wear, contamination, and long-term drift.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, including the standard ISO 4401-05 mounting pattern and Rexroth DR 10 series port configuration for drop-in replacement.
- Integrated Gauge Port: The “YM” variant includes a pressure gauge connection, enabling quick verification and fine adjustment of the 75 bar reduced pressure setting during commissioning and maintenance.
- Leak-Free Sealing: High-quality sealing elements and precision-machined mating surfaces minimize internal leakage and ensure consistent pressure regulation across the full operating range.
