Bosch Rexroth ZDR 6 DP2-43 75YM 12 Hydraulic Valve

The Bosch Rexroth ZDR 6 DP2-43/75YM/12 hydraulic pressure-reducing valve delivers precise downstream pressure control in industrial hydraulic circuits, limiting the secondary circuit pressure to a preset level to protect components and maintain stable operation. As part of Rexroth’s ZDR 6 family of sandwich-plate valves, this unit combines compact geometry with pilot-operated control for reliable regulation in tight spaces. The ZDR pressure-reducing family is designed as a cartridge valve that can be configured in screw-in or manifold-mounted installations to suit different system layouts, providing dependable secondary-pressure regulation across a range of applications. The 75YM/12 suffix indicates a specific mounting and porting configuration within Rexroth’s catalog, and related substitutions exist in the product line (for example ZDR6DP2-4X/75YM with the R900483786 designation in replacement catalogs). In practical terms, it is used to regulate pressure in a designated portion of a hydraulic circuit, helping to protect downstream components, stabilize actuator performance, and ensure consistent pressure delivery in demanding industrial environments.
