The ZDR6DP1-43/150YM-12V pressure reducing valve is manufactured by Bosch Rexroth within the ZDR Pressure Reducing Valves series and stabilizes downstream pressure in hydraulic automation circuits. Nominal size 6 keeps the component compact for tight manifold spaces, while sandwich plate mounting allows it to be stacked easily with other CETOP units. The porting pattern matches ISO 4401-03-02-0-05 so interchangeability with standard subplates is maintained. Pressure is reduced in channel P, and a rotary knob lets technicians set the desired value directly on the valve. Pilot oil is taken internally and returned externally to separate pilot flow from the main circuit. Secondary pressure is limited to 150 bar to protect connected actuators, and the housing withstands a maximum operating pressure of 350 bar.
A maximum flow rate of 50 l/min permits medium-capacity circuits without excessive pressure loss. Backpressure at port T can reach 160 bar, allowing elevated return-line pressures without disturbing regulation. The required oil cleanliness is ISO 4406 (c) 20/18/15 to preserve spool accuracy. The valve can be installed in any orientation, and FKM seals resist high temperatures and aggressive fluids common in industrial equipment. A check valve is not included, so reverse flow must be managed externally. The body lacks a locating hole, leaving alignment to the sandwich bolts, and a weight of 1.2 kg minimizes added mass in mobile or space-restricted assemblies.
