Bosch Rexroth ZDR6DA2-43 75Y Hydraulic Pressure Reducing Valve

Bosch Rexroth ZDR6DA2-43/75Y is a ZDR-series hydraulic pressure reducing valve engineered to lock downstream pressure at a pre-set level in industrial hydraulic circuits. The inline/intermediate-plate variant (listed in Rexroth catalogs as ZDR6DA2-4X/75Y) supports modular installation in plant manifolds and machines, delivering reliable pressure control where downstream tooling must see a stable pressure regardless of supply fluctuations. The 75Y suffix denotes this particular setpoint variant within the ZDR family; Rexroth catalogs also show available downstream setpoints across the range, including 25, 75, 150, 210, and 315 bar, enabling selection to match application needs. Identified listings for this model include R900410813 (pressure reducing valve intermediate plate ZDR6DA2-4X/75Y) and related Rexroth part numbers, confirming its role as a configurable, replaceable element in hydraulic systems. Typical applications include machine tools, hydraulic clamping, and test rigs where maintaining a defined secondary pressure is critical for performance and safety.
