The ZDC 10 P-2X/M pressure compensator is produced by Bosch Rexroth within the ZDC Pressure Compensators series. The valve stabilizes hydraulic actuators by holding a constant pressure drop across throttling elements in load-sensing circuits. Its direct operated actuation provides short response time without external pilot stages. The unit maintains a controlled differential pressure of 10 bar to ensure consistent flow regardless of load fluctuations. A nominal size of NG 10 matches medium-flow manifolds commonly found in mobile and industrial systems. The sandwich plate connection allows stacking between subplates following the ISO 4401-05-05-0-05 porting pattern so installation into standard valve banks is straightforward. With an internal pilot oil supply the valve simplifies circuit plumbing and reduces leakage points. Operating limits include 350 bar on ports a, b, and p, and it passes up to 85 l/min without exceeding the designed differential.
The maximum pressure on port T is 250 bar, while port Y is rated for 150 bar, giving designers clear boundaries for tank and drain lines. Standard paint provides basic corrosion protection suitable for sheltered machine frames. NBR seals resist common hydraulic oils and keep external leakage low. Cleanliness of the supply fluid must meet ISO 4406 class 20/18/15 to avoid spool wear and sticking. The compensator can be mounted in any position, which offers layout flexibility inside power packs. It fastens with four M6 screws to ISO 4762-10.9 specifications, delivering the clamp force required for high pressure stacking. Service weight is 3.0 kg, so a single technician can handle the component during assembly without lifting aides.
