Product Overview
The Rexroth DRC 5-52/200Y (Material No. R900917526) is a direct-operated, pilot-assisted pressure reducing valve engineered for precise secondary circuit pressure regulation in industrial hydraulic systems. Manufactured by Bosch Rexroth, this valve belongs to the proven DRC series of sandwich and inline pressure control valves, designed to maintain a constant reduced outlet pressure regardless of fluctuations in the primary supply pressure or changes in flow demand. The valve operates on a balanced spool principle, where the outlet pressure acts against an adjustable spring force to modulate the spool position, thereby throttling the flow to achieve the set reduced pressure. With a nominal pressure rating of 200 bar (designated by the “200Y” code), this valve is ideally suited for applications requiring reliable, repeatable pressure reduction in sub-circuits, clamping systems, and actuator control lines. Its robust construction and precision spool-to-sleeve fit ensure minimal hysteresis, excellent pressure stability, and long service life in demanding industrial environments.

Engineering Features & Advantages
- Precision Pressure Regulation: The balanced spool design ensures accurate and stable reduced pressure output, minimizing deviation even under varying inlet pressure and flow conditions.
- Low Hysteresis & Fast Response: Direct-operated pilot stage provides quick reaction to pressure changes, maintaining consistent downstream pressure for sensitive hydraulic circuits.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened spool and sleeve components resisting wear and contamination.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in installation without modification.
- Compact Sandwich Design: Space-saving construction allows integration into existing manifold stacks, reducing piping complexity and leak points.
Typical Industrial Applications
This pressure reducing valve is commonly deployed in plastic injection molding machines for mold clamping pressure control, metallurgical presses for precise force regulation in secondary circuits, CNC machine tools for tool clamping and counterbalance systems, and general industrial hydraulic power units where reliable reduction of system pressure to actuator or sub-circuit levels is required. It is also suitable for construction and marine hydraulic systems demanding robust,
