Product Overview
The Rexroth ZDR10DA2-55/210Y (Material No. R900406651) 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 the inlet (primary) pressure or changes in flow demand. As a sandwich-plate (module) style pressure control valve, it regulates secondary circuit pressure by throttling the flow through a precision control spool, making it an essential component for protecting downstream actuators, clamping circuits, and sub-systems from over-pressure conditions. The “DA” configuration denotes an externally adjustable pressure setting with a defined adjustment range, while the “210” pressure rating indicates a maximum secondary pressure setting of approximately 210 bar, suitable for demanding industrial hydraulic circuits operating on mineral oil-based fluids.
