ZDR10VP5-3X/200YMV/12

The ZDR10VP5-3X/200YMV/12 valve belongs to the ZDR Pressure Reducing Valves series from Bosch Rexroth. It maintains a regulated downstream pressure in hydraulic automation circuits. The unit is sized NG10, so it fits 10 mm manifold cavities and keeps assemblies compact. Its sandwich plate mounting allows direct stacking between adjacent plates, eliminating external pipework. The ISO 4401-05-04-0-05 porting pattern aligns with widely used subplates to simplify interchangeability. SAE code 12 connection threads accept standard fittings for auxiliary gauge or pilot lines. Pressure is reduced in the P channel, letting the designer control supply flow before it reaches sensitive branches. A sleeve with a hexagon head and a protective cap forms the adjustment element, making the set pressure easy to tune yet secure against tampering. An internal pilot oil supply shortens the control path, and an external Y return port keeps the spring chamber at tank pressure. Because the design omits a check valve, reverse flow must be routed through separate components.

The valve tolerates inlet pressures up to 315 bar, positioning it for high-pressure pump circuits. Its secondary line can be set as high as 200 bar, providing a stable controlled pressure to actuators downstream. A permissible counter pressure of 160 bar in the return path prevents unwanted lifting of the spool under back-pressure conditions. With a maximum flow of 100 l/min, the device supplies medium-flow machinery without excessive pressure drop. Correct function is guaranteed with hydraulic fluids having viscosities between 10 and 800 mm²/s, covering most mineral oil grades used in mobile and industrial plants. FKM sealing elements withstand chemical additives and allow fluid temperatures from –20 to +80 °C, so cold-start and elevated-temperature operation remain leak-free. To protect the precision throttle edges, fluid cleanliness must reach ISO 4406 class 20/18/15, which limits particle contamination. These combined limits on pressure, flow, temperature, and cleanliness confirm reliable pressure reduction across demanding duty cycles.
