The ZDR10DA1-5X/25Y/12 valve belongs to the ZDR Pressure Reducing Valves series and is manufactured by Bosch Rexroth. It limits pressure in hydraulic automation branches by throttling flow from the main supply to a secondary circuit. The model mounts as a sandwich plate between subplates and directional valves, so line piping is minimized. Its nominal size is 10, matching ISO cavities that handle medium flow rates. The porting pattern follows ISO 4401-05-04-0-05, enabling direct stacking with compatible manifold blocks. Pressure is reduced in channel A, and the spool follows the A2 to A1 symbol to direct pilot oil correctly. A rotary knob permits on-site adjustment of secondary pressure, which is rated at 25 bar for the downstream circuit. Pilot oil is taken internally while the drain is routed externally, preventing pressure buildup in the control chamber. The inlet side may see up to 315 bar without impairing function.
For water-glycol media the maximum operating pressure is 210 bar, ensuring seal integrity when HFC fluids are used. The valve tolerates a counter pressure of 160 bar at port T, maintaining stable regulation even when return lines are restricted. A maximum flow of 80 l/min can pass through channel A without exceeding the pressure characteristic limits. An integrated check valve (version A) allows reverse flow from the secondary side to the primary side, eliminating the need for an external bypass element. Five ports are provided to match standard hydraulic layouts, and a G1/4 gauge port 12 mm deep lets technicians monitor the controlled pressure locally. Acceptable fluids include mineral oils HL and HLP as well as the synthetic or biodegradable groups HETG, HEES, HEPG, HFC, HFDU, and HFDR, giving flexibility in system design. These features combine to support compact, high-performance pressure reduction in industrial hydraulic manifolds.
