The ZDC6XP-1X/8M-287 pressure compensator is produced by Bosch Rexroth within the ZDC Pressure Compensators series for hydraulic automation circuits. It operates on a direct operated principle and comes in nominal size 6, aligning with CETOP size D03. The mounting interface follows ISO 4401-03-02-0-05 and the porting pattern is DIN 24340 Form A. Channel P is load-compensated, and the spool symbol P2 → P1 indicates the regulated flow path. Maximum operating pressure is 250 bar, permissible flow is 35 l/min, and a set pressure differential of 8 bar is maintained.
The valve provides four ports and draws pilot pressure from port B to actuate the compensating spool. Installation orientation is unrestricted, so it can be mounted in any position inside a manifold stack. Sealing relies on NBR material, and fluid cleanliness must not exceed ISO 4406 class 20/18/15 to protect internal clearances. The assembly is secured with four M5 ISO 4762 grade 10.9 screws that fit the tapped holes on the interface.
