ZDB10VP2-4X/100V

The ZDB10VP2-4X/100V is part of the ZDB Pressure Relief Valves series produced by Bosch Rexroth for hydraulic automation circuits that require dependable pressure limitation. It follows component series 4X, and its sandwich plate construction lets users stack the unit between a subplate and other valve sections without extra piping. System pressure is adjusted by a sleeve that has a hexagon head and a protective cap, enabling safe manual tuning. The design is pilot-operated to keep the regulated pressure steady across a range of flows, while a single valve cartridge carries out the relief task. This cartridge can be set as high as 100 bar, providing a fixed ceiling that protects pumps, actuators, and piping when demand spikes.

The excess fluid is routed from port P to port T, defining the valve’s P–T relief function within a manifold. FKM sealing elements withstand mineral-oil based fluids in the HL, HLP, HLPD, HVLP, and HVLPD classes, so compatibility is maintained at higher temperatures and with detergent additives. The body is supplied without additional corrosion protection, meaning external surfaces must be shielded if the installation environment is aggressive. There is no locating hole, so alignment relies solely on the sandwich bolts holding the stack. This model is designated as a pressure relief valve, completing the specification set for applications that need compact over-pressure safeguarding without auxiliary corrosion or positioning features.
