Product Overview
The Rexroth DR 20-5-52/200YM is a pilot-operated pressure reducing valve designed to maintain a constant reduced outlet pressure regardless of fluctuations in the inlet (primary) pressure or changes in flow demand. Part of the renowned Rexroth DR series, this valve features a 20-size (NG20) housing and a 200 bar pressure rating, with the “YM” suffix indicating the specific adjustment and control configuration. In industrial hydraulic systems, it functions as a critical pressure control component, protecting downstream circuits, actuators, and instrumentation from overpressure while ensuring stable, repeatable operating pressure for precise process control.

Engineering Features & Advantages
- Precision Pressure Regulation: Pilot-operated spool design delivers highly accurate and stable reduced outlet pressure, minimizing hysteresis and pressure overshoot across varying flow conditions.
- Robust Pressure Control: Maintains constant secondary pressure independent of primary pressure fluctuations and load changes, ensuring reliable operation of downstream actuators and sensitive components.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a durable housing and precision-machined spool for long service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, allowing drop-in replacement without modification to existing manifolds or piping.
Typical Industrial Applications
This pressure reducing valve is widely deployed in heavy industrial hydraulic systems, including plastic injection molding machines where precise clamping and injection pressures are critical, metallurgical presses requiring controlled force application, CNC machine tools and machining centers for stable tool actuation, and general industrial power units where downstream circuits must be protected from excessive system pressure. It is also commonly found in construction and marine hydraulic systems demanding reliable pressure regulation under demanding duty cycles.
