Bosch Rexroth DR 30-5-52 200YM == 00597158. A139-276

Bosch Rexroth DR30-5-52/200YM is a pressure-reducing valve in the DR30 family, engineered to reduce upstream hydraulic pressure to a controlled downstream value within industrial hydraulic circuits, helping to stabilize actuator performance and protect system components from pressure spikes. It carries the material number 00597158 and is also referenced as A139-276, linking it to Rexroth's part catalogs and cross-reference listings used by distributors and service partners. As a DR30-5 variant, the valve is designed for compact installation in medium- and high-pressure hydraulic systems, where precise regulation of downstream pressure is required for predictable operation of tooling, presses, and automation equipment. Applications span hydraulic power units, test stands, and machine tools in manufacturing environments, with the DR30-5-52/200YM variant supporting Rexroth's standard spare parts ecosystem for upgrades and maintenance. Common services include inspection and replacement as part of Rexroth's spare parts program, ensuring continued compatibility with existing 200YM porting configurations.
