Product Overview
The Rexroth 3DR10P5-62/100Y/00M (Material Number R900916661) is a direct-operated, 3-way pressure reducing valve from the proven Rexroth 3DR series. It is designed to maintain a constant reduced outlet pressure regardless of fluctuations in inlet pressure or changes in flow demand. The valve operates on a balanced spool principle, where the adjustment element (spring-loaded poppet/spool assembly) modulates the connection between the inlet (P), outlet (A), and return (T) ports to regulate downstream pressure. As a 3-way design, it not only reduces pressure but also provides a relief function, venting excess downstream pressure to the tank port. This makes it ideal for systems requiring precise secondary pressure control, such as clamping circuits, pilot pressure supply, and actuator positioning systems. The “Y” in the model code indicates an external drain connection, ensuring stable operation independent of return line pressure. The valve is a direct-fit replacement for OEM Rexroth components and is widely used in industrial hydraulic power units and machine tool systems.

Engineering Features & Advantages
- Precision Pressure Regulation: The 3-way spool design maintains constant reduced outlet pressure with minimal hysteresis and fast response to flow or inlet pressure changes.
- Integrated Relief Function: Unlike 2-way reducers, the 3-way configuration actively vents excess downstream pressure to tank, preventing pressure spikes in closed-loop or clamping circuits.
- External Drain Stability: The Y-port external drain ensures the reduced pressure setting is unaffected by return line pressure fluctuations, providing reliable performance in complex manifold systems.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened spool and sleeve for long service life and contamination resistance.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, including mounting pattern, port locations, and pressure characteristics.
Typical Industrial Applications
This valve is commonly used in plastic injection molding machines for precise clamping force control, metallurgical presses for pilot pressure regulation, CNC machine tools for tool clamping
