The ZDR6DB2-4X/25YM/12 valve belongs to the ZDR Pressure Reducing Valves series and is produced by Bosch Rexroth for pressure control in hydraulic automation systems. It is built in nominal size 6 so it fits compact hydraulic manifolds. A sandwich plate mounting format lets it stack between subplates without separate piping. Its port connections follow ISO 4401-03-02-0-05, ensuring interchangeability across standard CETOP 03 patterns. The unit processes mineral oil HL or HLP defined by DIN 51524, aligning with common industrial fluids. Pressure is reduced from port P with pilot oil taken from port B, so the downstream branch receives controlled pressure while upstream flow remains unaffected. Internal pilot oil supply simplifies installation, and the secondary pressure is limited to 25 bar, while the housing tolerates operating pressures up to 350 bar.
Adjustment is made through a sleeve with a hexagon head protected by a cap, allowing secure setting changes during maintenance. An NBR seal package withstands petroleum-based fluids and temperature cycling. The design accommodates flows up to 50 l/min, supporting medium-capacity actuator circuits. Back pressure at port T can rise to 160 bar without affecting the regulated outlet, which broadens installation options near return lines. Leakage oil is routed externally, preventing case pressure buildup and aiding cooler return flow. Because it can be installed in any orientation, machine layout is not restricted. The required cleanliness level is ISO 4406 (C) 20/18/15, so filtration must limit particle contamination accordingly. The assembly is supplied without a check valve, meaning reverse flow must be handled by separate components if needed.
