The ZDR10VP4-3X/200YM/12 is manufactured by Bosch Rexroth within the ZDR Pressure Reducing Valves series and is applied to keep downstream pressure constant in hydraulic automation lines. It uses a nominal size 10 flow section, and its sandwich plate construction lets the unit be stacked between other CETOP modules without pipework. Compatibility is provided by the ISO 4401-05-04-0-05 mounting pattern, while the matching CETOP D05 and NFPA T3.5.1 R2-2002 D05 port layouts allow interchange with global manifold standards. Five ports are available, and the P2→P1 spool symbol indicates the controlled flow direction. Designers can choose an internal or external Y gallery for pilot supply and drain to suit circuit feedback needs. Pressure is set with a rotary knob identified as adjustment type 4, and all service connections use SAE size 12 threads to fit common hydraulic hoses quickly.
The valve’s pressure stage reaches 200 bar, permitting the user to dial outlet pressure up to this value with repeatable accuracy, while the body tolerates a maximum operating pressure of 315 bar on the inlet side to withstand high-pressure pumps. A counter pressure of 160 bar can be present at the return port without degrading regulation performance, and a maximum flow capacity of 100 l/min supports actuators that require moderate oil volume. NBR sealing elements are installed to resist standard mineral oils and keep leakage low over long duty periods. Overall weight is 2.3 kg, light enough for direct manifold support yet substantial enough to damp vibration. These parameters combine to deliver reliable pressure management in compact hydraulic stacks.
