Product Overview
The Rexroth ZDR10DP2-56/210YM (Material No. R900410876) is a direct-operated, pilot-assisted pressure reducing valve from the proven ZDR10 series, designed to maintain a constant reduced outlet pressure regardless of fluctuations in inlet pressure or changes in flow demand. As a sandwich plate (module) valve conforming to ISO 4401 / DIN 24340 size 10 (NG10 / CETOP 5), it regulates secondary circuit pressure by throttling flow across a precision control spool, with the spring-loaded spool continuously balancing against the adjusted set pressure. The valve is ideally suited for industrial hydraulic systems requiring a stable, reduced pressure branch — such as clamping circuits, pilot pressure supply, and actuator control loops — where downstream pressure must remain independent of main system pressure variations. The “210” designation indicates a pressure adjustment range up to 210 bar, and the “YM” suffix denotes the specific adjustment and seal configuration for this model variant.
