The ZDC16P2X/XM pressure compensator belongs to the ZDC Pressure Compensators series produced by Bosch Rexroth for hydraulic automation systems where a stable pressure differential is needed. It is built as a 2-way version marked “P,” so flow passes through two main ports while the valve balances pressure. A nominal size of NG16 defines the interface dimensions for integration with other NG16 components. The sandwich plate connection style lets the unit be stacked between other valve sections, and the ISO 4401-07-07-0-05 porting pattern matches common subplates to shorten assembly time. An external pilot oil supply keeps the control circuit separate from the main flow for consistent operation. The compensator can be installed in any position, giving designers freedom in manifold layout, and its 3.5 kg weight allows single-person handling during maintenance.
The valve supports a maximum flow of 150 l/min so it can regulate medium-capacity circuits without cavitation. It sustains operating pressures up to 350 bar at ports a, b, and p, enabling use in high-pressure drives, while port T is limited to 250 bar to protect return lines and port Y is limited to 150 bar to safeguard the drain path. A fixed pressure differential setpoint of 10 bar ensures that downstream flow remains constant even when load pressure changes. The required oil cleanliness level of ISO 4406 20/18/15 indicates the filtration needed to prevent spool wear. NBR seals, identified by the code M, provide compatibility with standard mineral-based fluids and resist leakage under the stated pressures.
