The ZDR6DA2-4X/80YV/60 pressure reducing valve belongs to the ZDR Pressure Reducing Valves series manufactured by Bosch Rexroth and is intended to stabilize downstream pressure in hydraulic automation circuits. Its nominal size 6 body keeps the installation compact, while a maximum input pressure of 315 bar enables use on high-pressure supply lines. The valve supports a flow of 50 l/min to ensure actuators receive adequate oil volume. An ISO 4401-03-02-0-05 porting pattern permits direct mounting on standardized subplates, and the reduced pressure is delivered through port A. Pressure is adjusted by a sleeve with a hexagon and protective cap so settings can be locked after commissioning. Pilot oil is taken internally and drained externally, which limits heat buildup in the main line, and leakage is directed to port T(Y) to prevent return-line pressure from affecting the set value.
An internal check valve allows unrestricted reverse flow, supporting bidirectional operation without separate plumbing. The /60 variant includes a locating hole that positions the block accurately on the manifold face. Four ISO 4762 M5-10.9 screws secure the unit, maintaining gasket compression at full working pressure. A G1/4 pressure gauge port, 12 mm deep, lets maintenance staff verify the adjusted value without extra fittings. Port T(Y) can handle 160 bar, accommodating circuits with elevated drain pressure. FKM seals resist heat and aggressive media, and the required fluid purity is ISO 4406 (c) 20/18/15 to minimize wear. The valve weighs 1.2 kg, making it straightforward to handle during installation and service.
