Product Overview
The Rexroth DR6DP2-5X/75YM (Material No. R900450964) is a direct-operated, pilot-assisted pressure reducing valve from the proven DR6DP series, designed to maintain a constant reduced outlet pressure regardless of fluctuations in the inlet (primary) pressure or changes in flow demand. As a 3-way pressure reducing valve, it reduces the system pressure in a selected branch circuit to a preset value while simultaneously providing pressure relief capability through its return connection, making it ideal for sub-circuit pressure regulation in complex hydraulic systems. The “5X” designation indicates the 50 to 59 series installation and connection dimensions, ensuring full interchangeability with current Rexroth production standards. The valve is set to a nominal reduction pressure of 75 bar, denoted by the “75YM” code, and is engineered for panel or manifold mounting in industrial power units, machine tools, and heavy-duty hydraulic drives where precise secondary pressure control is essential.

Engineering Features & Advantages
- Precision Pressure Regulation: The direct-operated spool design delivers accurate, repeatable reduced pressure control with minimal hysteresis, ensuring stable operation of downstream actuators and sub-circuits.
- 3-Way Pressure Limiting Function: In addition to reducing inlet pressure, the valve relieves excess secondary pressure back to tank, protecting downstream components from pressure spikes caused by thermal expansion or external loads.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a robust housing and hardened spool and seat components for long service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, including the 5X series connection pattern, allowing drop-in replacement without modification.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original REXROTH OEM standards, ensuring drop-in replacement without modification to existing manifolds or piping.
