Product Overview
The Rexroth DRC30-5-52/200Y (Material Number: R900504551) is a high-performance pilot-operated pressure reducing valve designed for demanding industrial hydraulic systems. Manufactured by Bosch Rexroth, a global leader in drive and control technology, this valve belongs to the DRC series of 3-way pressure reducing valves. Its primary function is to maintain a constant reduced outlet pressure (secondary pressure) regardless of fluctuations in the inlet pressure (primary pressure) or changes in flow demand. The “200Y” designation indicates a nominal pressure setting of 200 bar and a specific adjustment type, ensuring precise control in complex circuits where multiple pressure levels are required from a single power source.

Engineering Features & Advantages
- Precision Pressure Regulation: The pilot-operated design ensures highly accurate and stable secondary pressure control, minimizing pressure overshoot and hysteresis even under varying flow conditions.
- Integrated Safety Relief Function: As a 3-way valve, it not only reduces pressure from the primary side but also provides a relief path from the secondary side to the tank, protecting downstream components from pressure spikes caused by external forces or thermal expansion.
- Industrial Reliability: Built with a robust cast iron housing and hardened, precision-ground spool, this valve is engineered for continuous operation in severe industrial environments, offering excellent wear resistance and long service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring seamless integration into existing manifolds and systems without modification.
Typical Industrial Applications
This Rexroth pressure reducing valve is essential in hydraulic circuits requiring multiple pressure levels. Common applications include plastic injection molding machines (for clamping and injection pressure control), metallurgical presses, machine tool clamping systems, and test benches where precise secondary pressure regulation is critical for process accuracy and safety.
