The ZDR6DP2-4X/210YMV/12 pressure reducing valve belongs to the ZDR Pressure Reducing Valves series produced by Bosch Rexroth for hydraulic automation tasks that require a stable downstream pressure. It uses nominal size 6 passages and follows the ISO 4401-03-02-0-05 mounting pattern so it integrates with standard subplates. Flow paths correspond to CETOP size D03 for straightforward manifold interchange. Adjustment type 2 relies on a hex sleeve capped to prevent accidental changes, and pressure is reduced at port P. The spool symbol P2→P1 shows flow from the supply passage to the regulated outlet. Pilot oil is supplied internally and returned externally, which simplifies inlet plumbing while isolating the return line. The design has no check valve, and an SAE gauge port is provided for pressure monitoring.
The inlet can withstand 350 bar, while the secondary stage is limited to 210 bar to protect connected actuators. Back pressure at port T(y) may reach 160 bar without disturbing regulation accuracy. Maximum flow is 50 l/min, matching moderate circuit demands within a compact envelope. FKM seals resist heat and aggressive fluids, extending service life in challenging environments. The unit weighs 1.460 kg, allowing easy handling during manifold installation. These characteristics enable the ZDR6DP2-4X/210YMV/12 to deliver consistent pressure limitation in mobile and industrial hydraulic equipment.
