Product Overview
The Rexroth DR 10-5-52/315YM (Material No. R900597132) is a direct-operated pressure reducing valve designed to maintain a constant reduced outlet pressure regardless of fluctuations in the inlet pressure or changes in flow demand. As a member of the Rexroth DR series, this valve is a proven, high-reliability component used throughout industrial hydraulic systems to protect downstream circuits, actuators, and instrumentation from over-pressure conditions. The valve operates on a balanced spool principle: the outlet pressure acts on the spool against an adjustable spring force, and the spool modulates to throttle the flow and hold the secondary pressure at the set value. With a nominal size of NG10 (Size 10) and a pressure rating of 315 bar, the DR 10-5-52/315YM is engineered for demanding applications requiring precise, stable pressure regulation in a compact, leak-tight package.

Engineering Features & Advantages
- Precision Pressure Regulation: The direct-operated spool design delivers accurate, repeatable secondary pressure control with minimal hysteresis, ensuring stable operation of downstream actuators and sensitive components.
- Balanced Spool Design: The pressure-balanced spool minimizes the influence of inlet pressure variations on the reduced outlet pressure, providing consistent performance across the full operating range.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened, precision-ground spool and sleeve for long service life and resistance to contamination-related wear.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, including the ISO 4401 NG10 mounting pattern, allowing drop-in replacement without modification.
- Compact Subplate Construction: Space-efficient design simplifies integration into existing manifolds and hydraulic power units.
Typical Industrial Applications
The Rexroth DR 10-5-52/315YM pressure reducing valve is widely deployed in heavy industrial hydraulic systems where precise secondary pressure control is critical. Typical applications include plastic injection molding machines (clamping and injection circuits), metallurgical presses and rolling mills, CNC machine tools and machining centers, construction and marine hydraulic systems, and general industrial
