ZDR Series Direct-Acting Pressure Reducing Stacking Valves

Product Overview: The ZDR Series is an industrial-grade, direct-acting pressure reducing valve in a sandwich plate design. It is engineered to lower the high primary pressure of a hydraulic system to a stable, secondary pressure for specific branch circuits. Compliant with ISO 4401 mounting standards, these valves are stacked vertically beneath directional valves, significantly saving installation space and minimizing potential leak points. Whether it is the ZDR10-DP2 (Size 10) or the ZDR6-DP (Size 6), this series is renowned for its rapid response and pressure stability, making it ideal for machine tools and automated production lines.

Featured models on this page: ZDR10-DP2-5X/210YM, ZDR6-DP1-4X/25YM, and ZDR6-DP2-4X/150YM.

Key Technical Advantages:

• Compact Sandwich Plate Design: Allows for seamless integration into hydraulic manifolds without extra piping, optimizing system layout and reliability.

• Direct-Acting Rapid Response: The direct-operated architecture ensures instantaneous reaction to pressure fluctuations, maintaining precise dynamic stability in the secondary circuit.

• Versatile Pressure Stages: Available in multiple ranges, including 25 Bar, 150 Bar, and 210 Bar, to meet the exact force requirements of various actuators.

• Integrated Check Valve (YM): Models with the YM suffix feature a built-in check valve, allowing free reverse flow from the secondary circuit back to the primary line.
