The ZDC16P-2X/M pressure compensator belongs to the ZDC Pressure Compensators series from Bosch Rexroth and maintains a stable differential pressure in hydraulic automation circuits. With a nominal size of 16, it fits systems that need a mid-range passage area while keeping installation compact. A differential pressure setpoint of 10 bar stabilizes flow across metering edges so actuators receive consistent speed under changing loads. The valve permits a maximum flow of 150 l/min, supporting pumps and directional valves that feed multiple consumers. Channels a, b, and p withstand up to 350 bar, matching high-pressure supply lines in industrial machines. An internal pilot oil supply removes the need for external pilot piping. The sandwich plate connection integrates into stacked manifolds that follow the ISO 4401-07-07-0-05 pattern, and any mounting orientation is acceptable. A weight of 3.5 kg allows manual handling during service.
Oil must be filtered to ISO 4406 class 20/18/15 so the throttling gaps remain accurate over time. The unit accepts HL, HLP, HLPD, HVLP, or HVLPD fluids, letting users select standard or detergent-enhanced mineral oils. NBR seals contain these media and resist swelling. Continuous duty is allowed at fluid temperatures up to 80 °C, covering typical tank heater settings. The return port t is rated for 250 bar, preventing excessive back-pressure in closed-loop circuits. Viscosities up to 380 mm²/s are tolerated, ensuring dependable starts in cold conditions. Together, these limits enable the compensator to maintain constant flow when paired with flow control or proportional valves in machinery where load pressure fluctuates.
