Bosch Rexroth DZ 10-1-30 210YM 5 Hydraulic Pressure Reducing Manual Valve

Bosch Rexroth DZ 10-1-30 210YM 5 hydraulic pressure reducing valve is a compact device in Rexroth’s DZ 10 family that lowers a higher system pressure to a pre-set secondary level within a hydraulic circuit. The 210YM suffix denotes a configuration rated for downstream pressure up to 210 bar, a specification documented in related Rexroth ZDR 10-series variants such as ZDR10DB1-5X/210YM. This valve serves to stabilize downstream pressure, protecting actuators and pilot-operated devices from fluctuations and enabling reliable, steady control in hydraulic circuits. Common applications include conditioning pressure for cylinders, linear actuators, and valve manifolds in industrial machinery, where precise, consistent pressure limits are essential for safe and predictable operation. The DZ 10 size indicates a compact footprint suitable for space-constrained installations while delivering accurate regulation across a range of flows typical for mid-range industrial systems. Related Rexroth configurations show how port patterns and mounting options vary by variant, with some models using ISO bore patterns on X and Y ports and ending in 5X/210YM to identify the 210 bar class.
