Product Overview
The Rexroth ZDR 10 DA2-54/150Y (Material No. R900410884) is a direct-operated, pilot-assisted pressure reducing valve from the proven ZDR 10 series, designed to maintain a constant reduced outlet pressure regardless of fluctuations in the inlet pressure or changes in flow demand. As a sandwich-plate style pressure control valve, it limits the pressure in a secondary circuit to a preset value, protecting downstream actuators, cylinders, and precision components from overpressure. The “DA2” designation indicates a direct-operated reducing valve with a specific adjustment and spring range, while the “150Y” suffix defines the pressure rating and adjustment type. This valve is engineered for panel or manifold mounting within industrial hydraulic power units and is widely deployed where accurate secondary pressure regulation is critical.

Engineering Features & Advantages
- Precision Pressure Regulation: Direct-operated spool design maintains a constant reduced outlet pressure with minimal hysteresis and fast response to load changes, ensuring stable secondary circuit performance.
- Integrated Pressure Relief Function: The valve incorporates an internal relief feature that protects the reduced pressure side against excessive pressure spikes, enhancing system safety.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened spool and sleeve for long service life and contamination tolerance.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM Rexroth ZDR 10 series standards, allowing drop-in replacement without manifold modification.
- Compact Sandwich Design: Space-saving NG10 sandwich construction simplifies stacking with directional and flow control valves on a common manifold.
Typical Industrial Applications
This Rexroth ZDR 10 pressure reducing valve is commonly used in plastic injection molding machines for clamping and injection pressure control, metallurgical presses for secondary circuit regulation, CNC machine tools and machining centers for tool clamping and counterbalance circuits, and general industrial hydraulic power units where precise reduced pressure is required for pilot circuits, clamping devices, and actuator protection.
