The ZDR10VP5-3X/200YM/12 pressure reducing valve is produced by Bosch Rexroth in the ZDR Pressure Reducing Valves series. It maintains a fixed secondary pressure in hydraulic circuits and is suited for automation tasks where precise pressure regulation is required. The unit belongs to component series 3X and has nominal size 10, enabling compatibility with ISO 4401-05-04-0-05 mounting interfaces. Pressure reduction is carried out at port P1, and the set value can be trimmed with a hexagonal bushing that is protected by a cap. The valve limits the downstream line to 200 bar while receiving pilot oil internally and discharging it externally. There is no check valve fitted, and the complete assembly weighs 2.3 kg.
The valve tolerates a maximum operating pressure of 315 bar on the inlet side and handles flow rates up to 100 l/min without losing stability. Counter pressure at ports TA and TB may reach 160 bar, allowing use in return lines with moderate backpressure. Connection threads follow SAE standards to simplify pipework in mobile or industrial equipment. NBR seals are installed, restricting continuous operation to fluid temperatures not exceeding 80 °C. Proper function also requires hydraulic oil cleanliness to ISO 4406 class 20/18/15 to prevent wear of throttling edges. These limits combine to define safe operating margins for the ZDR10VP5-3X/200YM/12 in pressure control loops of hydraulic machinery.
