The ZDC10P-2X/M pressure compensator belongs to the ZDC Pressure Compensators series from Bosch Rexroth and is intended to stabilize flow in hydraulic automation circuits. The sandwich plate design enables direct stacking between other components, while the ISO 4401-05-05-0-05 porting pattern aligns the internal galleries without adapters. An internal pilot oil supply removes the need for an external pilot line, reducing manifold drilling. The pressure differential setpoint is fixed at 10 bar so the valve maintains a steady pressure drop across the metering edge regardless of load changes. For system resilience, the compensator tolerates a maximum operating pressure of 350 bar on ports A, B, and P and can pass up to 85 l/min, which suits medium-capacity cylinders or motors. Because the installation position can be any orientation, designers can place the section wherever space permits without affecting performance.
The unit weighs 3.0 kg, allowing manual handling during manifold assembly. Required oil cleanliness is ISO 4406 class 20/18/15, which limits particle contamination and preserves the throttling land from wear. Fluid temperature may range from −20 °C to +80 °C when using NBR seals, giving adequate margin for mineral-based hydraulic oils. Port T is rated for 250 bar and port Y for 150 bar so back-pressure in the tank or drain lines cannot exceed those limits. Secure attachment is made with four M6-10.9 screws conforming to ISO 4762, providing proper clamping force to prevent leakage between sandwich layers. The NBR seal material offers compatibility with standard petroleum fluids and maintains elasticity across the stated temperature window. These characteristics help the ZDC10P-2X/M deliver stable flow control while fitting compactly into high-pressure manifolds used in presses, machine tools, and mobile work functions.
