The ZDR10DP1-5X/150YMV valve belongs to the ZDR Pressure Reducing Valves series and is manufactured by Bosch Rexroth for hydraulic automation where stable downstream pressure is required. It is built in nominal size 10 (NG10), giving it a medium flow path suitable for general industrial circuits. The unit follows the D05 Cetop size so it drops directly onto standardized subplates, while the ISO 4401-05-04-0-05 mounting interface aligns the porting underneath the body. Five ports support separate connections for supply, reduced pressure, pilot, drain, and measurement services within the same block. A rotary knob provides manual adjustment so technicians can fine-tune the setting during commissioning. The valve can cap the secondary pressure at 150 bar to protect cylinders and motors downstream, yet it withstands 315 bar at the inlet to survive high-pressure mains. A maximum flow of 80 l/min keeps response fast without excessive pressure loss under full load.
The design omits a check valve, so reverse flow returns through the main gallery without additional components. Leakage oil is routed to port TA, preventing pressure build-up in the pilot housing. Pilot oil is taken from the internal supply and returned externally, isolating the control chamber from back pressure in the return line. A G1/4 pressure gauge port is provided so operators can verify the regulated pressure during operation. Pressure reduction occurs in port P, and the spool symbol P2 → P1 illustrates the flow path from the high-pressure side to the controlled outlet. FKM seals resist mineral oils and elevated temperatures to extend service life. The assembled body weighs 2.54 kg, making it light enough for single-person installation on a manifold.
