Product Overview
The Rexroth ZDR6DA2-4X/150YM is a direct-operated, three-way pressure reducing valve from the proven ZDR6 series (Series 4X), designed to maintain a constant reduced outlet pressure regardless of fluctuations in the inlet (primary) pressure or changes in flow demand. As a three-way design, it not only reduces pressure but also provides secondary-side pressure relief by venting excess pressure to the tank port, ensuring stable downstream pressure regulation in demanding hydraulic circuits. The valve is manufactured by Bosch Rexroth, a global benchmark in industrial hydraulics, and is widely deployed as a precision pressure control component in machine tools, presses, injection molding equipment, and general industrial power units.

Engineering Features & Advantages
- Precision Pressure Regulation: The direct-operated spool design delivers accurate, repeatable reduced pressure control with minimal hysteresis, protecting sensitive downstream actuators and circuits from pressure spikes.
- Three-Way Relief Function: In addition to reducing inlet pressure, the valve relieves excess secondary-side pressure to the tank, preventing pressure build-up during load changes or thermal expansion.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a robust housing and hardened internal components for long service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, ensuring drop-in replacement on CETOP 3 / NG6 subplates without modification.
Typical Industrial Applications
The Rexroth ZDR6DA2-4X/150YM is commonly specified in plastic injection molding machines, metallurgical and hydraulic presses, CNC machine tools, and general industrial power units where a stable, reduced secondary pressure is required for clamping, positioning, or pilot circuits. Its three-way relief capability also makes it suitable for accumulator charging circuits and systems subject to varying load-induced pressure fluctuations.
