The ZDR6DP2-32/75YM/12 valve is produced by Bosch Rexroth as part of the ZDR Pressure Reducing Valves series. It maintains a controlled secondary pressure in hydraulic automation circuits. Nominal size 6 defines the port dimensions, while an ISO 4401-3 mounting pattern lets the unit bolt directly to standardized subplates. Pressure reduction occurs at port P, and the spring chamber is kept at 75 bar secondary pressure. An internal pilot oil supply senses inlet conditions, and external pilot oil return removes pilot flow without influencing downstream pressure. The device accepts up to 315 bar at the inlet, and regulation is adjusted with a sleeve fitted with a hexagon and cap that permits secure setting. The assembly weighs 1.2 kg, easing manual installation inside compact manifolds.
The valve handles line flows up to 50 l/min without losing control accuracy. Backpressure at port T may reach 160 bar, so downstream circuitry can operate at elevated tank pressures. NBR seals are used throughout the body to resist common hydraulic oils. A dedicated SAE gauge port thread permits the attachment of a pressure indicator for commissioning and service. The body contains no integral check valve, and it includes no locating holes, reducing machining work on the mating manifold. Installation is possible in any orientation, enabling flexible placement inside machines. These characteristics let the ZDR6DP2-32/75YM/12 provide reliable pressure reduction while accommodating varied flow, tank pressure, and mounting requirements found in industrial hydraulic equipment.
