ZDR10DA2-5X/210YMV/12

The ZDR10DA2-5X/210YMV/12 valve belongs to the ZDR Pressure Reducing Valves series from Bosch Rexroth and is designed to maintain stable downstream pressure in hydraulic automation systems. Its nominal size 10 sets the internal flow passages to suit medium-duty circuits where space and capacity need to balance. A CETOP D05 interface offers compatibility with common subplates, while the sandwich plate mounting type lets the unit stack between other directional or throttle elements. The mounting pattern ISO 4401-05-04-0-05 ensures bolt alignment with standardized manifolds. Pressure is adjusted through a sleeve with hexagon and a protective cap, allowing secure setting changes during service. The valve endures a maximum inlet pressure of 315 bar so it can be installed on high-pressure supply lines, yet it limits secondary pressure to 210 bar to protect sensitive actuators. Pressure reduction occurs in channel A, directing regulated oil to the work port without affecting other circuit legs.

The maximum flow of 80 l/min defines the volume the valve can pass while holding the selected pressure, supporting moderate pump outputs. A counter pressure limit of 160 bar at port T specifies the allowable back pressure so return lines do not interfere with regulation accuracy. Pilot oil is taken internally and returned externally, which separates control flow from tank lines to improve stability when manifold back pressure fluctuates. A G1/4 pressure gauge port, 12 mm deep, provides a point to verify the reduced pressure during commissioning. FKM (Viton) seals resist high temperature hydraulic fluids and many synthetic oils, extending service life. No check valve is included, so reverse flow must be handled by external components when required. The spool symbol A2→A1 identifies flow direction through the regulating stage for circuit diagrams. A weight of 2.56 kg helps designers account for manifold loading and facilitates manual handling during installation.
