The ZDR10DA2-5X/150YV/12 valve belongs to the ZDR Pressure Reducing Valves series from Bosch Rexroth and serves to maintain a stable secondary pressure in hydraulic automation circuits. It fits NG10 manifolds because its nominal size is 10. Installation is carried out as a sandwich plate according to ISO 4401-05, allowing direct stacking between subplate and actuator blocks. An internal pilot with an external drain path marked Y supports accurate pressure reduction without influencing tank line pressure. Secondary pressure can be set up to 150 bar so downstream actuators stay within safe force limits. The inlet side tolerates 315 bar, enabling the unit to work on high-pressure supply manifolds. Adjustment occurs through a sleeve with a hexagon and cap, which lets maintenance staff lock the chosen setting. Fluid passes through the A2 reduced port so only the targeted branch is regulated.
The ZDR10DA2-5X/150YV/12 handles up to 80 L/min, providing sufficient flow for medium-capacity cylinder or motor branches. A built-in check valve prevents reverse flow when the primary circuit depressurizes. Back pressure at port T can reach 160 bar, which means the drain line may share return headers carrying elevated pressure without disturbing regulation. A dedicated gauge port with an SAE thread marked /12 simplifies connection of diagnostic transducers. The housing is sealed with FKM elastomers so the valve resists high-temperature mineral or synthetic oils. Permissible fluids include HL, HLP, HETG, HEPG, and HEES categories, allowing use with mineral, ester, or glycol-based media. Fluid cleanliness must meet ISO 4406 class 20/18/15 to avoid spool wear and maintain consistent pressure behavior.
