Bosch Rexroth ZDR 6 DP2-43 25YM 12 Hydraulic Pressure Reducing Valve Sandwich Plate

The Bosch Rexroth ZDR 6 DP2-43/25YM/12 is a direct-operated, pressure-reducing valve in a sandwich-plate configuration designed to stabilize downstream hydraulic pressure in compact circuits. It lowers the secondary-circuit pressure to a preset value and uses ISO 4401-compatible porting to simplify installation in stackable valve blocks. The valve mounts on a CETOP D03 footprint, enabling tight integration with other Rexroth components in a multi‑valve assembly. Typical ZDR 6 configurations feature four through ports arranged in the sandwich-plate pattern, with bore passages sized to support reliable mid‑range flow (port bore around Ø12.2 mm). As part of the ZDR 6 family, this model provides precise downstream pressure control to protect actuators and downstream components from upstream fluctuations and pressure spikes. Common applications include machine tools, hydraulic clamping circuits, presses, and other industrial hydraulics where consistent, preset pressure is essential. The DP2-43/25YM/12 variant combines the 6‑size body with the DP2-43 porting and the 25YM/12 material/installation codes to suit embedded sandwich-plate installations in standard hydraulic manifolds.
