The ZDR6DA2-4X/75YV/12 valve belongs to the ZDR Pressure Reducing Valves series from Bosch Rexroth and serves to hold a stable downstream pressure in hydraulic automation systems. It is nominal size 6, defining its mounting footprint, and follows the ISO 4401-03-02-0-05 porting pattern to align with standardized subplates. Four ports are provided so the component can be placed in circuits that need separate pressure, return, and gauge lines. Port A is designated as the pressure-reduction outlet, and the internal flow route is represented by spool symbol A2→A1. The pressure setting is adjusted through a sleeve with a hex and a protective cap, allowing secure tool access without tampering. Pilot oil is taken from the internal supply and drained externally to keep pilot flow clean. The valve can be installed in any position, which simplifies manifold layout.
The valve withstands an input pressure up to 315 bar while limiting the secondary circuit to 75 bar, supporting applications that need consistent pressure reduction. Maximum flow capacity is 50 l/min, and the counter pressure at port T(y) may reach 160 bar without affecting regulation. A built-in check valve permits free reverse flow when necessary. A G1/4 gauge port is included for local measurement of the reduced pressure. FKM seals resist common hydraulic fluids and elevated temperatures. The required oil cleanliness is ISO 4406 class 20/18/15 to protect internal surfaces and maintain reliability. These characteristics let the valve integrate into compact servo manifolds while preserving accurate pressure control.
